"Repay" is a defective verb. Thinking about it, how about remembering the concept referring to “defectives”? Defective verbs are those that do not have complete conjugation, in view of the tenses and people that make up the verb conjugations in general. It is also important to know that this non-existence is due to morphological and euphonic factors (referring to the sound that a given word produces when pronounced).
Thus, in order to clarify the communicative intention that guides the article in question, let us analyze the following statement:
Me compensation all damage caused by the collision.
Here, when we analyze the euphonic aspects arising from the verb to refund (now inflected in the example), we find a certain abnormality. Thus, we see why it is considered defective (which is why there is no possibility of a complete conjugation). Therefore, let's see in full how it is conjugated:
Indicative mode
verb to reimburse
In the present indicative mode, there is only the first and second person plural
Subjunctive Mode
Subjunctive of the verb to reimburse
In the subjunctive mode, the present tense has no verbal persons
Imperative
Imperative mode
affirmative imperative
Imperative of the verb to reimburse
In the affirmative imperative, there is only the second person plural
negative imperative
There are no verbal people integrating this time
Personal infinitive
Inflected infinitive of the verb to reimburse
In the personal infinitive there are all verbal people
Nominal forms
Nominal forms of the verb to reimburse
Nominal forms are represented by the gerund, participle and infinitive
Given all the peculiarities, especially the non-conjugation of certain modes, times and verbal people, it is recommended that, in view of the issuer's intention, in certain circumstances, the substitution of the verb under study by another is made, synonym. Examples of this are the verbs “indemnify”, “repair”, “compensate”, among others.
So, let's go back to the previous example, reformulating it:
Me repair all damage caused by the collision.
