The objective of the study is to investigate the difficulty of using irregular verbs in the students writing an essay at the University of Babylon.

   The design of this study is descriptive qualitative research. The sample of the study comprised 25 students in their fourth year, and it was selected randomly. The findings of the study showed that 70% of the students were unable to use irregular cases such as verbs and adjectives incorrectly.  Also, the findings show that the students use both regular and irregular verb (past) in their students' writing essays. The most dominant verb past written by the students in their students’ writing essay is an irregular verb. Regular verbs are verbs that can change according to tense and  change it  regularly. Regular verbs are verbs whose changes comply with normal rules, that is with add the letter -d or -ed to the verb first-form/verb-1  (infinitive)  so  that  it  becomes  a  verb  form  second/verb-2  (past tense). Several things must be considered in the way of  forming regular  verbs by adding the letter -ed suffix or -d in the basic verb/verb-1 (infinitive). Irregular verbs are verbs  that  change  according  to  the  tense  and  do  not  comply  with  normal compliance. The past tense Irregular verbs are not formed from basic verbs/verb-1 (infinitives) plus letters -d or -ed letters to  form verb-2/past tense.  Irregular verbs form their past tense differently (through) not always) through a vowel and consonant change.  This study recommends students should be well-trained on how to use irregular verbs in the past tense case or changing the form of the regular adjective, and also must be memorized by the learners/students because of the difficulty  to distinguish the irregular verbs among the sentences.
