ti

Put mid-tone ti after the subject and before the predicate. The object, if present, follows the lexical verb. Ti remains a separate word and takes no person or number ending.

• Bísí ti ra bàtà. — Bísí has bought shoes.
• A ti rí àpò náà. — We have found the bag.
• Àwọn ọmọ ti jí. — The children have woken up.
• Yàrá náà ti mọ́. — The room is clean now.

The first three examples present events as already reached. The fourth presents cleanliness as attained: a bare property statement describes cleanliness, while ti makes the reached state relevant. Attainment can apply to a state as well as an action: the room has become clean.

Ti alone supplies neither an exact date nor a duration. It also combines with ń for a continuing situation already begun; a rule saying every ti situation is entirely finished would therefore be too broad.

For 'not yet', learn kò tíì as an established construction. Preserve mid-tone aspectual ti versus high-tone relative tí. Similar-looking possessive material belongs to another frame, so spelling and position must be considered together.
