Alright already, enough of the only one "t" sound in the word important.

116. Depends, that "t" is usually expressed as a subtle* pause not followed by the tongue tapping "tuh" sound, similarly...

to the first "t" in important.

Perhaps, as a matter of stress on the importance of the word, the first "t" might receive a full blown "tuh" sound, im-por-Tant. "It is important to steer the car away from oncoming traffic.", or, "We interrupt this program for an important message from NOAA about a tornado in your front yard." I would have a very difficult time lending credibility to any full-grown person saying imporunt when advising about imminent public danger.

*"subtle" is, clearly, a word that deserves mockery. It's, obviously, the result of a misprint which the original printer was too ashamed/narcissistic to correct. At this point, "subtle" would be over-the-moon to be pronounced "sub-ul" or even "su-ul" (the latter of which is fast on the way).
