doesn't mend
The original sentence provided is, "He will lose all his wealth if he doesn't mends his ways." We need to examine the underlined part, "doesn't mends," and determine if it is grammatically correct and how to improve it if necessary.
The phrase "doesn't mends" is found in the conditional clause ("if he doesn't mends his ways"). Let's look closely at the grammar involved.
In English, when we use auxiliary verbs like 'do', 'does', 'did', and their negative forms 'don't', 'doesn't', 'didn't', the main verb that follows must be in its base form (the infinitive without 'to').
Therefore, "doesn't mends" is grammatically incorrect. The verb "mends" includes the '-s' ending which is already accounted for by the auxiliary verb "doesn't".
Let's consider the given options to find the correct way to phrase the underlined part:
Based on the analysis, the phrase "doesn't mend" correctly replaces "doesn't mends". The improved sentence is:
"He will lose all his wealth if he doesn't mend his ways."
| Auxiliary Verb (Negative) | Subject Example | Main Verb Form | Correct Example |
|---|---|---|---|
| do not (don't) | I, You, We, They, Plural nouns | Base Form | They don't go. |
| does not (doesn't) | He, She, It, Singular nouns | Base Form | He doesn't go. |
| did not (didn't) | All subjects | Base Form | She didn't go. |
| Concept | Explanation | Application Here |
|---|---|---|
| Subject-Verb Agreement | The verb must agree with its subject in number (singular/plural) and person (1st, 2nd, 3rd). | 'He' is 3rd person singular, requiring 'does'/'doesn't'. |
| Auxiliary Verbs + Main Verb | After 'do', 'does', 'did', 'don't', 'doesn't', 'didn't', the main verb is always in its base form. | After 'doesn't', use the base form 'mend', not 'mends'. |
| Conditional Sentences (Type 1) | If + present simple, will + infinitive. Used for real or likely conditions and their results. | "If he doesn't mend..." (present simple negative) + "...he will lose..." (will + infinitive). |
The sentence structure "If + present simple, will + base verb" is typical of a Type 1 Conditional sentence. This type is used to talk about a real or possible situation in the future and its likely result.
Understanding conditional sentences helps ensure that the verb tense and form in both parts of the sentence are correct. The correction we made ("doesn't mend") ensures the verb in the 'if' clause is correctly formed in the present simple tense for the subject 'he'.
