Morphology

think + twice

The meaning 'to consider something carefully' is directly derivable from 'think' + 'twice' because 'twice' signals doing the thinking more than once (repeating or pausing to reconsider), which conveys extra caution. This literal compositional logic is common across languages and follows a straightforward pattern, so a B1 learner who knows both words will very likely infer the MWE's meaning.

Etymology

The phrase think twice creates a clear image: you think once and then again to check your choice. So it means 'to consider something carefully before acting'.
