7.3B 'Till' (or 'until') and 'by' [> LEG 7.34] 1 Some verbs naturally refer to 'periods of time' or 'continuity' [> 9.5B]: e.g. learn, lie, live, rain, sit, sleep, stand, stay, wait and work. 2 Till (or until) and by mean 'any time before and not later than'. We cannot use by at all with these 'continuity' verbs. (Not *I'll wait here by 5 o'clock. *) We can only use till (or until) with these verbs: I'll wait here till (or until) 5 o'clock. I won't wait here till (or until) 5 o'clock. 3 We use by with verbs which do not refer to periods of time.

She'll arrive at 6. 4 We use till or until with 'point of time verbs' only in the negative. She won't arrive till (or until) 5. (But not *She will arrive till 5.*) Write: Supply by or till. 1 I'll wait... Monday before answering his letter. 2 I intend to stay in bed... 10 o'clock tomorrow morning. 3 Your suit will be ready...
