Sense: adjective/1
Hourly specifies an exact interval of sixty minutes, making it the most precise of these words. Regular is broader — it can mean any fixed pattern (daily, weekly, monthly) or an evenly spaced rhythm. Frequent does not guarantee equal intervals at all; something can happen every few minutes (frequent) but not regularly or hourly. Daily is the closest sibling in structure: both refer to a specific clock or calendar interval, but daily (every 24 hours) is far more common and cannot substitute for hourly when scheduling public transport or medical routines. For example: 'The hourly bus runs more often than the daily express.'

Etymology
Formed from 'hour' (from Old French 'hore', from Latin 'hōra', from Greek 'hōrā' meaning a season or time of day) plus the suffix '-ly', which turns nouns into adjectives and adverbs indicating 'every [noun]'. The word entered English around the 15th century, first as an adverb ('once an hour') and later as an adjective ('occurring every hour'). The wage-related sense developed alongside industrialisation when employment shifted from daily or piece-rate to per-hour pay.
