-o - English
Pronunciation
Suffix
-o (plural -os or -oes)
- A colloquializing suffix, typically appended to names, abbreviations of long words, or substantive uses of adjectives.
Usage notes
-o generally does not change the meaning of the word or name but only makes it more colloquial, as with cheapo and Jacko. It is often appended to clipped or elided forms of longer words, as with ambo and parmo. Occasionally, the terminal consonant of the clipped form is doubled for clarity of meaning or pronunciation, as with uggo and doggo. It sometimes does change the meaning of words, usually by being applied to adjectives to indicate a person with a pronounced trait, as with weirdo (“weird person”), or to nouns used metonymously to indicate a person with a pronounced connection to the other object, as with wino (“poor or vagrant alcoholic”). Especially in American English, some uses of this suffix are understood as dated slang, as with bucko and neato. The suffix is most frequently and widely encountered in Australian English, which has additional uses (such as rego for registration and nasho for national service) that are never or only extremely rarely encountered in other dialects.
Its meaning is very similar to some uses of -y and its use is particularly common where use of -y might cause misunderstanding, as with randy and rando, journey and journo, whiny and wino.

1At least one use of the archaic "sigmatic future" and "sigmatic aorist" tenses is attested, which are used by Old Latin writers; most notably Plautus and Terence. The sigmatic future is generally ascribed a future or future perfect meaning, while the sigmatic aorist expresses a possible desire ("might want to"). It is also attested as having a rare sigmatic future passive indicative form ("will have been"), which is not attested in the plural for any verb. 2The present passive infinitive in -ier is a rare poetic form which is attested. 3At least one rare poetic syncopated perfect form is attested.
