PAA:
I commend you on the triplical impressive feat...
“Triplical” is not (really) a word. Wiktionary has no entry for it and any instances of its use found on Google appear to be either in error or as a proper noun in some obscure historic context.
“Triplicate,” if that is what you meant, would be incorrect in this instance – it does not refer to non-identical things or sets thereof.
“Triple” would have been the right word, even if it
isn’t sesquipedalian enough for your taste.
Also, “triple” would correctly have been after “impressive,”
not before.
That is hardly an excuse. [Insert sarcasticon if desired.]
Please explain your use of sarcasm here.
