Synonym discussion
Sense: adjective/1
All four words describe something large or important, but they differ in nuance. 'Considerable' focuses on an amount that is large enough to have a real impact — it carries a slightly neutral tone. 'Significant' emphasizes meaning or importance beyond just size: a significant discovery matters because of its implications. 'Substantial' suggests solid, physical largeness — a substantial meal fills you up, a substantial income covers all your needs. 'Sizable' is the most informal and is used mostly for countable quantities: a sizable crowd, a sizable profit. Choose 'considerable' when you want to stress that the size or degree is noteworthy but not extreme; use 'significant' when the importance is the main point; pick 'substantial' for physical or financial bulk; and use 'sizable' in casual contexts about numbers. A single donation of NT$50,000 could be described as both 'a considerable sum' and 'a sizable donation', but only 'a significant contribution' would also highlight its effects on a project.

Etymology
The word comes from Latin 'considerabilis', meaning 'worthy of consideration'. It entered English in the 1400s with that literal meaning — something deserving thought. Over the 1600s and 1700s, the sense shifted: if something was 'worthy of consideration', it was usually because it was large or substantial, and the word gradually came to mean 'large in amount' on its own. The two senses (adjective and noun) both developed from this same root, with the noun arising as a convenient shorthand for 'a considerable quantity'.
