From -culus (diminutive suffix).
- nominative neuter singular of
- accusative masculine singular of
- accusative neuter singular of
- vocative neuter singular of
From (with anaptyxis) Proto-Italic *-klom, from Proto-Indo-European *-tlom, from *-trom. Compare stabulum, which comes from a similar suffix *-dʰlom. Despite the resemblance, osculum (which besides is never found in the form **osclum) and other diminutive nouns do not contain this suffix.
- Suffix used to form some nouns derived from verbs, particularly nouns representing tools and instruments.
Second-declension noun (neuter).
