Are you semantical?

I once had a college professor tell me that I had a keen sensitivity to semantics.

So, I had to go online and look it up:

Main Entry: se·man·tics
Pronunciation: si-'man-tiks
Function: noun plural but singular or plural in construction
1 : the study of meanings: a : the historical and psychological study and the classification of changes in the signification of words or forms viewed as factors in linguistic development b (1) : SEMIOTIC (2) : a branch of semiotic dealing with the relations between signs and what they refer to and including theories of denotation, extension, naming, and truth
2 : GENERAL SEMANTICS
3 a : the meaning or relationship of meanings of a sign or set of signs; especially : connotative meaning b : the language used (as in advertising or political propaganda) to achieve a desired effect on an audience especially through the use of words with novel or dual meanings

Main Entry: general semantics
Function: noun plural but singular or plural in construction
: a doctrine and educational discipline intended to improve habits of response of human beings to their environment and one another especially by training in the more critical use of words and other symbols

I guess that is a good thing, since it was a graphic design class. So, are you semantical?
