The verb "lend" is an irregular verb in English, meaning to give something to someone temporarily, expecting it to be returned. Its conjugation deviates from the regular pattern.

In the present simple tense, "lend" follows its base form for most subjects: "I lend," "you lend," "he/she/it lends," and so on. For example, "She lends her books to friends frequently."

In the past simple tense, "lend" changes to "lent." This irregular form is used to talk about actions of giving something temporarily that were completed in the past. For instance, "He lent me his car for the weekend."

The past participle of "lend" is also "lent." When forming perfect tenses, such as the present perfect or past perfect, the past participle is combined with auxiliary verbs. An example sentence is "They have lent their support to the project."

"Lend" is typically used as a transitive verb, meaning it requires a direct object to complete its meaning: "She lent her phone to a friend."

The verb "lend" can also be used in various idiomatic expressions and phrasal verbs, such as "lend a hand" (to help) and "lend an ear" (to listen).

Understanding the irregular conjugation of "lend" is essential for accurately describing actions of temporary giving. Its use in many idiomatic expressions adds to its richness in the English language.
