To eat. In the deep south of India It is polite to ask someone if they have had their breakfast or lunch. Rather than eat, the word take is often used.

Ambiguous in the context of school or college exams:
To 'take an exam' might mean either of the following:
(a) You are a teacher conducting the exam (typical Indian usage)
(b) You are a student writing the exam (typical Western usage)

In either case, it is the opposite of give.
