Synonym Chooser

How is the word deep different from other adjectives like it?

The words broad and wide are common synonyms of deep. While all three words mean "having horizontal extent," deep may indicate horizontal extent away from the observer or from a front or peripheral point.

a deep cupboard
deep woods

Where would broad be a reasonable alternative to deep?

The meanings of broad and deep largely overlap; however, broad is preferred when full horizontal extent is considered.

broad shoulders

When is it sensible to use wide instead of deep?

In some situations, the words wide and deep are roughly equivalent. However, wide is more common when units of measurement are mentioned, or when applied to unfilled space between limits.
