sense, since

A sense can be any one of the faculties: taste, touch, hearing, smell, sight, or equilibrium. It can also mean “understanding” or “perception.”

Since means “from a certain point in time up until now.” The word since can act as a preposition (since that time), as an adverb (she has since remarried), and as a subordinating conjunction (he hasn’t worked since he finished school).

As a subordinating conjunction, since does mean “because,” contrary to a popular but misguided myth.

Example: Since the accident, he has developed a keen sense of danger.

See as, because, since, for
