Over hundreds of years, English grammar developed different forms of many irregular verbs. The verb sink became:
- Present: sink
- Past: sank

Unlike many English words, the difference is not caused by spelling changes between countries. Instead, it is part of the normal grammar of an irregular verb.
Today, dictionaries around the world follow the same standard forms.
