-tella

Etymology

 * the first suffix was adapted by analogy from the causative meaning, taking to "to refer to as" as well as probably later "to act like", while the -ella is a frequentative suffix. The analogy may have also taken place only after the use of -tella in its literal (causative-frequentative) sense for some verbs.

Usage notes
Often added to the plural stem of the base noun.
