Etimologia

roller = early 15c., "rolling pin," agent noun from roll, c.1300 in intrans. sense of "to move by rotating;" late 14c. as "to move (something) by turning it over and over".

crush = mid-14c., from O.Fr. cruissir (Mod.Fr. écraser), variant of croissir "to gnash (teeth), crash, break," perhaps from Frankish *krostjan "to gnash" (cf. Goth. kriustan, O.Swed. krysta "to gnash").

-er = English agent noun ending, corresponding to L. -or. In native words it represents O.E. -ere (O.Northumbrian also -are) "man who has to do with," from W.Gmc. *-ari (cf. Ger. -er, Swed. -are, Dan. -ere), from P.Gmc. *-arjoz. 7
