It is sometimes interesting that we have so many words--so many synonyms and nuances--of common words, such as love and hate, yet so few words for other common concepts.

I haven't hit a synonym finder yet, but the idea of 'daily' is certainly very, very common, yet are there many words that are synonymous with it? Yes, diurnal, 'day by day,' and 'day-in, day-out' (sort of)...

What others might there be?
