Synonym discussion
Sense: adjective/1
All five words describe something becoming larger, but they differ in tone and typical use. 'Growing' is the broadest and most neutral, covering size, quantity, and intensity — a growing population, growing concern, growing pile. 'Increasing' is similarly broad but slightly more formal and more common in scientific or statistical writing. 'Rising' focuses on upward movement of measurable quantities, especially prices, temperatures, or numbers (rising costs, rising sea levels). 'Expanding' emphasises spread across area or scope (expanding business, expanding waistline). 'Mounting' carries urgency and is used for problems, debts, or pressure that accumulate to a worrying degree (mounting evidence, mounting frustration). For everyday use, 'growing' is the safest choice; choose 'mounting' when you want to convey tension or risk.
Etymology
The word 'growing' started as the present participle of the Old English verb 'grōwan', which meant 'to flourish, increase, or develop'. This verb came from Proto-Germanic '*grōaną', related to the ancient idea of plants becoming green and thriving. By the Middle English period (around the 13th century), speakers began using the '-ing' participle form as an adjective before nouns — first for plants, then gradually for anything that increases.
