The Learning Journey: Past Tense and Past Participle

Introduction

The use of past tense and past participle is essential in communication, especially in written language. It indicates that an event or an action has already happened, it gives a sense of time and sequence, and it allows us to express ourselves more accurately. In this article, we will explore the use of past tense and past participle, and how to form them in different verbs.

Past Tense

The past tense is used to describe an event or an action that has already happened. It is commonly formed in regular verbs by adding -ed at the end, while in irregular verbs it varies. For example, in regular verbs like “walk” and “play”, the past tense would be “walked” and “played”. In irregular verbs like “go” and “eat”, the past tense would be “went” and “ate”. However, there are exceptions to these rules, and some verbs have a different form for the past tense than from just adding -ed. For instance, verbs that end in a consonant + y change the y to i before adding -ed, like in “try” to “tried”. Additionally, some verbs have the same form for both the present and past tense, like “cut”. Lastly, some verbs have a completely different form altogether, like “be” to “was/were”.

Past Participle

The past participle is used when forming the present perfect, past perfect, and future perfect tenses, and it is also used as an adjective. It is commonly formed in regular verbs by adding -ed at the end, while in irregular verbs it varies. For example, in regular verbs like “walk” and “play”, the past participle would be “walked” and “played”. In irregular verbs like “go” and “eat”, the past participle would be “gone” and “eaten”. Like in forming the past tense, there are exceptions to these rules, and some verbs have a different form for the past participle than just adding -ed. For instance, some verbs that end in -e would drop the -e before adding -ed, like in “drive” to “driven”. Also, some verbs might have the same form as the past tense, like “cut”. Lastly, some verbs have a unique form altogether, like “be” to “been”.
