agglutinate (v.)
1580s, "unite or cause to adhere," from Latin agglutinatus, past participle of agglutinare "fasten with glue," from ad "to" (see ad-) + glutinare "to glue," from gluten "glue," from PIE *glei- (see glue (n.)). Related: Agglutinated; agglutinating. Perhaps suggested by the earlier use of the same word in English as a past-participle adjective (1540s) "united as by glue," from the Latin past participle.
