Meaning and Usage
"拡張" (かくちょう) means "expansion" or "extension" and is commonly used in contexts involving increasing size, capacity, or scope. It is often seen in technology (software, hardware), urban development, and general growth situations.
Common Collocations
- 拡張機能 (かくちょうきのう): "extension feature" often used in software to describe add-ons or plugins.
- 拡張メモリ (かくちょうめもり): "expanded memory," referring to additional computer memory.

Usage Notes
"拡張" is a noun but often used in compound nouns or with verbs like "する" (to do) to indicate the act of expanding. It is a formal term suitable for technical and business contexts. Avoid confusing it with "拡大" (かくだい), which also means expansion but often implies enlargement in a more physical or visual sense.
Learner Tips
When using "拡張," think about systematic or planned growth rather than spontaneous or casual increase. For example, software updates or city planning use "拡張," while simply making a photo bigger might use "拡大."
