Ways to annoy your English teacher.

Talk like an American

You can "blue", "yellow" or "purple" something. For whatever reason, "whiten", "blacken" and "redden" have the suffix "-en".

<<Well I don't think things like "shouldn't've" or "should've" are justified as written forms, because it's already established that "have" has a reduced form [@v] (as in, say, "Should he have done it?").>>

I'd say it is justfiable to write "should've" as a written form because it can occur at the end of sentences while the [@v] form of "have" doesn't occcur asentence finally.

"I know we should have" /aI n7U wi: SUd h{v/

vs.

"I know we should've /aI n7U wi: Sud@v/

"I know we have" /aI n7U wi: h{v/, never said as */aI n7U wi: @v/
