-illa

-illa f (noun-forming suffix, plural -illes)

1. diminutive suffix for feminine nouns
2. forms feminine nouns meaning "type of"

• “-illa”, in Gran Diccionari de la Llengua Catalana, Grup Enciclopèdia Catalana, 2024

Originally a variant of -ella used on verbs ending in -ata, -ota, -ätä, having developed by vowel contraction: -Aðele- (-oðele-) > -A.ele- (-o.ele-) > -Aile- (-oile-). Denominal use has been innovated in literary Finnish in the 20th century.

-illa (front vowel harmony variant -illä, stem -ile-, linguistic notation -ile- or -illA)

1. Forms frequentative verbs. The resulting verb often describes a more or less leisurely or long-lasting activity, or an activity that is not overly goal-oriented.

   ‎salata (“to keep a secret”) + ‎-illa → ‎salailla (“to be secretive”)

2. Forms action verbs which denote an activity closely related with a noun.

   ‎auto (“car”) + ‎-illa → ‎autoilla (“to drive a car”) (but not ˣautota)

   ‎maja (“hut”) + ‎-illa → ‎majailla (“to stay temporarily”) (but not ˣmajata)

   ‎pallo (“ball”) + ‎-illa → ‎palloilla (“to play a ball game”) (but not ˣpallota)

-illa f (noun-forming suffix, plural -illas)

1. added to feminine nouns to denote a diminutive form

   Synonyms: -ita, -cita

   Coordinate term: -illo

• If the noun has a final vowel (usually -a), it is dropped before adding -illa.
• In most cases, -illa is used simply to indicate a small or endeared thing, without changing the basic meaning of the noun; however, in some cases, it is used to effect a greater change in meaning, such as bombilla (“light-bulb”), from bomba (“bomb”).
• Different nouns tend to prefer different diminutive suffixes (see synonyms), though some nouns accept multiple diminutives and there is often regional or personal variation.
• For masculine nouns ending in “-a”, there is some alternation between the gender-reflecting diminutive -illo and the ending-reflecting diminutive -illa. When the latter is used, -ill- may be considered an infix.
