ot-

1. Converts a transitive verb into an intransitive verb with an agent-like argument, variously with reflexive, reciprocal, or passive meaning.

This prefix takes the following forms:

• ot- when stressed before a u and sometimes before o or a
• at- when unstressed before a u and sometimes before o or a
• os- when stressed sometimes before an e, o, or a
• as- when unstressed sometimes before an e, o, or a
• o- usually before an e, in which case the e itself is lost and the prefix is always stressed; some verbs with e take both an o- variant and an os-/as- variant, with different meanings
• e- before an i or y, and sometimes before a consonant
• ai- sometimes before a consonant
• ò- sometimes before a consonant

Some verbs beginning with a consonant can show variation between all three of the last options.
