Understanding Irregular Verbs in English

Before diving into see, it’s important to understand what makes a verb irregular. Unlike regular verbs, which follow the simple “-ed” pattern for the past tense and past participle, irregular verbs change unpredictably.

For example:

Regular verb: walk → walked → walked
Irregular verb: see → saw → seen

Irregular verbs are common in English, and many essential verbs, like go, do, eat, and take, are irregular. Their unique forms must be memorized because they don’t follow standard rules.

Why does see fall into this category? Simply put, English evolved from multiple languages, and many old forms stuck. This is why we say “saw” instead of “seed” for past tense.

Knowing irregular verbs helps you speak fluently, write correctly, and understand native English quickly. Using the wrong form of see can make sentences sound awkward or grammatically incorrect.
