Here's why:
* Focus on base form: Dictionaries primarily focus on the base form of a verb, which is the infinitive form (e.g., "to walk", "to eat").
* Contextual understanding: The tense of a verb is usually determined by its context in a sentence, not by the dictionary entry itself.
* Space constraints: Including all tenses for every verb would take up a significant amount of space in a dictionary.
However, some dictionaries may include:
* Sample sentences: These sentences demonstrate how the verb is used in different contexts, providing clues about its tense.
* Information on irregular verbs: Dictionaries often list the irregular forms (past tense and past participle) of irregular verbs.
To find out the tense of a verb, you need to analyze its context within a sentence.
For example, in the sentence "I walk to school every day", the verb "walk" is in the present tense.
