Esan is one of the numerous languages of the Kwa subdivision of the Niger-Congo language family, one of Africa's largest subgroups. Unlike English, Esan is a tone language (like many of its neighbouring settlements) not unlike Chinese. Dictionaries and grammar texts of the Esan language are being produced, which may help the Esan appreciate their written language. There is a high level of illiteracy among the Esan, and a large number of dialects, including Ẹkpoma, Ẹkpọn and Ohordua. Most annual Esan Kings' Council meetings are largely conducted in English for this reason.
Linguistic finding has shown the word ‘gbe’ to have the highest number of usages in Esan, with up to 76 different meanings in a normal dictionary. Names starting with the prefixes Ọsẹ; Ẹhi, Ẹhiz or Ẹhis; and Okoh (for male), Ọmọn (for female) are the commonest in Esan: Ẹhizọkhae, Ẹhizojie, Ẹhinọmẹn, Ẹhimanre, Ẹhizẹle, Ẹhimẹn, Ẹhikhayimẹntor, Ẹhikhayimẹnle, Ẹhijantor, etc; Ọsẹmundiamẹn, Ọsẹmhẹngbe, etc; Okosun, Okojie, Okodugha, Okoemu, Okouromi, Okougbo, Okoepkẹn, Okoror, Okouruwa, etc. To any Oko-, 'Ọm-' the suffix of the name can be added to arrive of the female version e.g. Ọmosun, Ọmuromi, etc.
All Esan nouns begin with vowel letters (i.e. a, e, ẹ, i, o, ọ, u): aru, eko, ẹbho, itohan, ozẹ, ọrhia, uze, etc. Due to the influence of neighbouring tongues and Western languages, especially English, there is the tendency among Esan to pronounce many non-Esan nouns beginning with a consonant letter. In the event of such within the boundary of Esan write-up, an apostrophe may be employed before the first consonant letter both to Esanize and ease the pronunciation. In speech however such apostrophe is often pronounced as ‘i’ /i: /: ’bazaar, ’Jonah, ’labour, ’zoo, etc.
Each Esan noun ends in either a vowel letter (e.g. ato, Ẹkpoma, uri, oya) or the vowel-associated letter ‘n’: agbọn, eran, ẹnyẹn, itọn, isẹn, etc. Exception to this rule is the writing of proper nouns where a name can end in letter ‘r’ always after a letter ‘ọ’ to make it sound like ‘or’ in English as well as the use of letter ‘h’ after a letter ‘o’ to make it sound as ‘oh’ in English: Isibor, Oko'ror, Okoh, Okoọboh, etc.
In nouns, following the first vowel letter is always a second consonant letter: ahoho, avan, ilo, udia. For the expression of a feminine gender, the second consonant letter following a vowel letter is doubled: ahhihi (=female ant), ọsshọ (=female friend), ọrrhia (=female person), etc. This gender-sensitive style is better understood by French speakers, who usually differentiate genders – masculine, feminine, neuter. Exception to this rule has to do with certain nouns that consist of vowel letters only e.g. 'oẹ' (leg, plural 'ae'), 'oo' (mother), 'uu' (death), etc.
Pluralization in Esan is of two forms, the first of which has to do with nouns that have original plural forms, in which case the first letter is replaced/displaced by another letter:
Ọmọn (baby), Imọn (babies);
Ọmọle (man, male), Imọle (men, males);
Okpea (man), ikpea (men);
Okhuo (woman, female), Ikhuo (women, females);
Ọshọ, ọmuọe (friend), ishọ, imuọe (friends);
Obhio (relation), ibhio (relations);
Obhokhan (child), ibhokhan (children);
Oghian (enemy), ighian (enemies);
Usẹnbhokhan (boy), isẹnbhokhan (boys);
Ọmamhẹn, ọmọhin (girl), imamhẹn, imọhin (girls);
Ọwanlẹn (elder, adult), iwanlẹn (elders, adults);
Ọrhia (person), erhia (persons);
Ọbo (doctor), ebo (doctors);
Ebo (English citizen), Ibo (English citizens);
Obọ (arm), abọ (arms);
Oẹ (leg), ae (legs);
Use (nail), ise (nails);
Udo (stone), ido (stones)
The second has to do, not with the above which have original plural form but, with a large number of other nouns which do not. In this case, a suffix (as the use of ’s’ in English) is used by adding it to the noun in question, but without a change in pronunciation. For example:
Uwaebe (school), uwaebeh (schools);
Eran (stick), eranh (sticks);
Emhin (something), emhinh (some things)
The use of Esan is open to three orders or arrangements: (subject-verb-object (SVO), object-subject-verb (OSV), and object-verb-subject (OVS)) to express themselves Okoh ’h gbi ele (SVO). Okoh imẹn ddaghe (OSV). Ena yẹ imẹn (OVS). SVO is commonest and most employed. The use of OVS is restricted to a limited number of grammatical constructions.
All Esan verbs start with consonant letters and end in either vowel letter or the vowel associated letter ‘n’: bi, dẹ, fan, hẹn, lolo, etc. In expressing the past, doubling of initial letter of a verb takes place such that ‘bi’ changes to ‘bbi’ and ‘hẹn’ becomes ‘hhẹn’. A verb can also begin with a diphthong: khian, gbe, bhanbhan. The formation of past tense in this case is not different: kkhian, ggbe, etc. Some Esan dialect such as Uzea makes use of ‘ah’ (or ’h) to show present participle (as in “He is going home.”). Although this is absent in majority of Esan dialects, it is used and placed before the main verb when writing: Ele ’h khọa = They’re having bath.
An Esan adjective, as does an English adjective, modifies a noun or pronoun. That is, it gives more information about a noun or pronoun and makes its meaning more specific. It can appear before or after a noun. The only difference between Esan and English adjectives is that like Japanese, some Esan adjectives are verb-like in that they inflect to show tenses: Ele mhẹnmhin. = They are good. // Ele mmhẹnmhin. = They were good. The doubling of the initial letter of the adjective 'mhẹnmhin (good)' like verbs, clearly demonstrates this point. Esan adjectives are of two distinct types: ‘word adjective’ and ‘phrasal adjective’.
A word adjective is an adjective consisting of a single word: esi, khọlọ, hu, jian, etc. This form of adjective is subdivided into five types: pre-noun adjective, post-noun adjective, numeral adjective, nounal adjective, and restricted adjective. A pre-noun adjective appears only before the noun it modifies, provides information about the noun’s size and/or quantity, and they start with a vowel letter: ukpomin, ekitui, udede, ikwẹkwi, etc. These adjectives are not subject to the law of tenses and do not take the suffix ‘mhin’. A post-noun adjective comes immediately after the noun it modifies: khọlọ, khọriọn, fuọ, ba, to, han, lẹnlẹn, bhihi, hu, khisin, khere, re(le) (far), re (deep), re (grown up), re (well attended), bue, tan, etc. These adjectives are subject to the law of tenses such that they are used to reflect time (e.g. “Okoh rẹ kkhọriọn.” = "Okoh is ugly.").
Except the adjective ‘khọriọn’, all others can be used with the suffix ‘mhin’, and (‘ebe’ and ‘esi’ which are also called noun adjectives) they all start with consonant letters. A numeral adjective is one that can be used to answer such question as “how many?”: ọkpa, eva, ea, igbe, etc. Because they are also nouns, they all start with vowel letters. They are neither subject to the law of tenses nor can they be used with the suffix ‘mhin’. A nounal or noun adjective is one that comes before a noun and can easily be manipulated to become a noun in usage: esi, ebe. It can neither be used with ‘mhin’ nor are they subject to tense law. A restricted adjective is one that can only be used with a particular noun e.g. ‘bhibhi’ in 'ewewẹ bhibhi' (early morning).
Some adjectives that can be placed under the word adjective are adjectives that are formed from the doubling of a word adjective: fanọn-fanọn (unkempt; untidy), rughu-rughu or ragha-ragha (disorderly), sankan-sankan (muddy and rough), yagha-yagha (untidy), kpadi-kpadi (rough or even), ose-ose (beautiful). This system can also be used thus: fanọn/2, yagha/2, kpadi/2, sankan/2, ose/2, etc.
A phrasal adjective is one that consists of more than one word; it is made up of a phrase. More often than not, an adjectival phrase usually contains either a noun + verb or an adjective+preposition+noun which combine to perform the work of an adjective. Some common examples are: rui ẹlo (blind), yi ehọ (deaf, rebellious), di ọmalẹn (old, senile), di itọn a (wretched), bhọn ose (beautiful), fi ahiẹ a (serene), fua amẹn (light-complexioned), ba bhi egbe (painful), mhẹn bhi egbe (body-friendly), mhẹn bhi unu (sweet), mhẹn bhi ẹlo (beautiful or not offensive to sight), mhẹn bhi ihue (not offensive to the nose), mhẹn bhi ehọ (not offensive to the ear), khọ bhi unu (unpalatable; offensive), khọ bhi egbe (unbearable), etc.
