A (highfalutin) word for a highfalutin word? [duplicate]

To illustrate the question, badroit used the word "meretricious" meretriciously.

Is there an English word that describes highfalutin words like "meretricious" that are (gratuitously) used in place of better-understood words like "garish"?

The word may or may not be self-describing.

Solution 1:

Sesquipedalian literally means 'a foot and a half long', and was originally applied to unnecessarily long words (in Latin); it has expanded in English to include people who use such words.

Solution 2:

In addition to TimLymington's excellent sesquipedalian, you might consider also grandiloquent. Its meaning tends more towards bombastic, so use just a dash if it fits your recipe. :-)
