Sense: adjective/2
All four words describe a lack of lightness, but they differ in scope and connotation. 'Serious' is the broadest term — it covers everything from a serious illness to a serious conversation, without implying emotional depth. 'Sincere' focuses on honesty and absence of deceit; you can be sincere about something trivial. 'Solemn' carries a formal, almost ceremonial gravity — a solemn promise feels weightier because of the occasion, not necessarily because of personal conviction. 'Earnest' sits between 'serious' and 'sincere': it adds the idea of deep personal commitment and emotional intensity. For example, a student could be serious about passing an exam, sincere when apologising for being late, solemn during a graduation ceremony, but earnest about pursuing a career in medicine — the last implies real personal dedication that goes beyond the situation.

Etymology
The word comes from Old English 'eornoste' meaning 'serious, zealous,' which itself comes from a Proto-Germanic root '*ernustuz' carrying the sense of 'vigour, struggle.' The noun meaning 'deposit' or 'pledge' (sense 3) developed separately from a different Old French root 'ernes' (a variant of 'arres' meaning 'earnest money'), which traces back to Latin 'arra' ('pledge'). Over time the two strands — the serious-attitude strand and the deposit strand — converged under the same spelling in Middle English.
