== English ==
=== Suffix ===
-culum
(no longer productive) Alternative form of -cule (diminutive suffix).
== Latin ==
=== Pronunciation ===
(Classical Latin) IPA(key): [kʊ.ɫũː]
(modern Italianate Ecclesiastical) IPA(key): [ku.lum] (stressed on the antepenult)
=== Etymology 1 ===
See the etymology of the corresponding lemma form.
==== Suffix ====
-culum
inflection of -culus:
nominative/accusative/vocative neuter singular
accusative masculine singular
=== Etymology 2 ===
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, ōsculum (which besides is never found in the form **ōsclum) and other diminutive nouns do not contain this suffix.
==== Alternative forms ====
-clum, -crum, -ulum
==== Suffix ====
-culum n (genitive -culī); second declension
suffix used to derive nouns from verbs, particularly nouns for tools and instruments
Synonyms: -men, -mentum, -tōrium, -ium
prōpugnō, prōpugnāre (“to fight for, defend”) + -culum → prōpugnāculum (“bulwark, fortress, protection”)
dēvertō, dēvertere (“to turn aside, turn away; to lodge”) + -culum → dēverticulum (“byroad; digression; lodging; refuge”)
===== Usage notes =====
The main form of this suffix is -culum, but various alternative forms exist. Most tend to be found in particular phonological contexts:
-crum can be found only if /l/ is present somewhere earlier in the word, as in lavācrum. It developed from Proto-Italic *-klom by long distance dissimilation (compare -ālis and its allomorph -āris). However, the non-dissimilated form -culum can also be found in some words with preceding /l/, such as liāculum.
-trum is found whenever the suffix occurs immediately after /s/, as in haustrum. In addition, it is found in some words that contain a liquid /r/ or /l/ somewhere earlier, such as arātrum, tālitrum; this type of formation seems to have been old and unproductive in Classical Latin. It was inherited from the Proto-Indo-European variant form *-trom. Apart from the limited occurrence of the ending in inherited Latin vocabulary, it has been used to coin neologisms, at first with influence from the cognate Greek instrument noun suffix -τρον (-tron), later (in Neo-Latin) with influence from modern English inanimate agent nouns ending in -er or -or (such as computer) and similar formations in other modern European languages.
-ulum is found whenever the suffix occurs immediately after a velar plosive (spelled c or g), as in cingulum. It is debated whether it comes from phonetic simplification of *-tlom after a plosive, or from the neuter of the etymologically distinct suffix -ulus (found in some agent nouns, such as figulus (“potter”)) from Proto-Italic *-elos. This ending can also occur after non-velar plosives, as in dēcipulum from dēcipiō.
-rum is found after two stems that contain /l/ and end in a plosive: fulcrum and scalprum. It seems to originate from either *-tlom (with liquid dissimilation as in -crum) or *-trom, with simplification after a velar or labial plosive (as possibly in -ulum).
The form -culum tends to be used in the remaining cases: it can be found after vowels (forming a number of common words in -āculum from first-conjugation verbs and some in -iculum from third-conjugation verbs) and after -r-.
The suffix -bulum (dissimilated form -brum) is etymologically related and has a similar meaning. It is typically found after a vowel. There are no obvious conditions for when it is used instead of -culum/-crum.
Most of the endings listed above have variant first-declension feminine forms, such as -cula, -tra, -ula, -bula, -bra (as in pavīcula, mulctra, dēcipula, sūbula, dolābra). Variant second-declension masculine versions of these endings are much less common, but are attested in a few nouns, such as culter, scalper (a variant of scalprum), arāter (a rare variant of arātrum), and the plural rastrī.
