Thanks for using those words.These words will help me to increase my vocabulary.

What error have you made (again) in the part I have marked in red?

You should forget about the big words in that message and focus on more useful ones.

"Polysyllabic" and "gobbledygook" are less obscure words than "benightedly" and "supercilious". You're quite likely to see and hear the former words in fairly everyday contexts.
