In plain English: Growth is when something gets bigger or develops over time.
"The growth of the city has transformed the entire neighborhood over the last decade."
Usage: Use growth to describe any positive increase in size, quantity, value, or strength over time. It applies broadly to living things expanding, populations rising, or economic figures climbing.
Growth comes from the verb grow combined with the suffix -th, which forms abstract nouns. Like its relatives in Germanic languages such as Old Norse and Middle High German, it originally referred to fresh vegetation or crops before entering English with this meaning.
