The pronunciation of any word in English (or any language at all) is not Universal.  This is because there are many different dialects of The English Language — both throughout America, and also world-wide.  The pronunciations that are presented on GiveMeSomeEnglish!!! are based-upon a combination of both “common usage”, and the most neutral accent used in The International Common Tongue — a.k.a. “American English”.

Adequate – For this word:  the “A” is short;  the “d” is a flap-d;  the “e” turns into an i-schwa;  the “qu” combination is pronounced like the “kw” combination;  and for the “-ate” suffix –the “a” turns into an i-schwa, the “t” is (usually) stopped, and the final “e” is silent (this is one of TWO standard pronunciations of this suffix in The Common Tongue).

– /æ-dih-kwih[t]/ – /ˈæ.ɾə(ɪ).kwə(ɪ)[t]/ – Notice also that the stress is on the first syllable and that the “t” ending (when not stopped) acts as a separate syllable –
