3 ambiguous sentences
Sometimes sentences with only are ambiguous (they can be understood in more than one way).
I only kissed your sister last night. (The sense can be 'only kissed', 'only your sister' or 'only last night'.)
In speech, the meaning is usually clear because the speaker stresses the part of the sentence that only refers to. Even in writing, the context generally stops sentences like these from being really ambiguous. However, if necessary only can be put directly before the object, complement or adverbial expression that it refers to. This is rather formal. Compare:
They only play poker on Saturday nights. (could be ambiguous) They play only poker on Saturday nights.
They play poker only on Saturday nights.
The meaning can also be made more precise with a relative structure.
Poker is the only game (that) they play on Saturday nights. Saturday nights are the only time (that) they play poker.
4 only today etc
Only with a time expression can mean 'as recently as', 'not before'. I saw her only today - she looks much better.
My shoes will only be ready on Friday.
Only then did she realise what she had agreed to.
For invened word order after only, as in the last example above, see 302.
