Definition of ‘Sink,’ ‘Sank,’ and ‘Sunk’
To properly differentiate between “sank” and “sunk,” we need to define the verb “sink” and its various forms. Sink is a verb that means to descend below the surface of water or another liquid; to fall or drop to a lower level; or to become submerged or engulfed. The verb “sink” is an irregular verb, meaning that its past tense and past participle forms do not follow the standard -ed ending rule.
Sank is the simple past tense form of “sink.” It is used to describe an action that occurred and was completed at a specific time in the past. It indicates a completed action without reference to duration or connection to the present.
Sunk is the past participle of “sink.” The past participle is used in perfect tenses (e.g., present perfect, past perfect, future perfect) and in passive voice constructions. It also functions as an adjective in some cases.
Structural Breakdown
Understanding the structural breakdown of the verb “sink” is essential for correct usage. The principal parts of the verb “sink” are:
- Base Form: sink
