There are no 7-letter words with those letters, there are a few 6-letter words though:grieveregivereviewviewerweever
elitist
jetsam
There are three 7-letter words possible:roosterrooterstoreros
Parades
cribbed
Except you gave us 11 letters that spell "celebrating."
Those letters can be used to spell "exigent".
The six-letter word that can be spelled with the letters "etlucte" is "cultet." However, "cultet" is not a standard English word. The correct word you may be looking for is "cutlet."
