Usage Note

In standard English, 'tomorrow' as an adverb does NOT take a preposition before it. Say 'I will see you tomorrow', NOT '~~I will see you on tomorrow~~'. This is different from many other time expressions (e.g., 'on Monday', 'in the morning').

Common Mistakes

I will call you on tomorrow.
I will call you tomorrow.
'Tomorrow' as an adverb does not need a preposition in front of it.
Tomorrow will be rain.
It will rain tomorrow.
Weather conditions require 'it' as the subject, not 'tomorrow'.

Synonym discussion

Sense: noun/2

While 'future' (未來) is the broadest and most neutral term for all time yet to come, 'tomorrow' (明天 in this sense — more figuratively 未來) carries a warmer, more hopeful tone and is often used in inspirational or visionary contexts ('a better tomorrow', 'the leaders of tomorrow'). 'Morrow' (次日／翌日) is an archaic or literary variant of 'tomorrow', now used mainly in fixed phrases like 'good morrow' or poetic writing. 'Days to come' (未來日子) is slightly more formal and often suggests a longer, unspecified span ahead. For everyday reference to the next calendar day, only 'tomorrow' works — you cannot say 'I will see you future' or 'I will see you morrow'.

Etymology

Old EnglishMiddle EnglishEnglish

The word 'tomorrow' comes from Old English 'tō morgenne', meaning 'on the morrow' (the following day). 'Tō' meant 'at' or 'on', and 'morgenne' was the dative form of 'morgen' (morning). So the original meaning was literally 'on the morning' of the next day. Over time, the meaning expanded from just the morning to the entire following day, and eventually to the future in general. By Middle English, it had fused into the single word 'tomorwe', later becoming 'tomorrow'.
