Character Breakdown

Meaning and Usage

"補強" (ほきょう) means "reinforcement" or "strengthening." It is often used in contexts where something is being physically strengthened, such as buildings or structures, but it can also be used metaphorically, like reinforcing arguments or team strategies.

Common Contexts

  • Construction and engineering: reinforcing buildings or materials to withstand stress or damage.
  • Sports: strengthening a team’s defense or lineup.
  • Communication: reinforcing explanations or evidence.

Collocations and Patterns

  • 建物の補強 (たてもののほきょう): reinforcement of a building
  • 守備の補強 (しゅびのほきょう): strengthening defense
  • 説明を補強する (せつめいをほきょうする): to reinforce an explanation

Usage Notes

"補強" is a formal noun often used in written and professional contexts. It can be combined with verbs like "する" to form "補強する" (to reinforce). Learners should note that it is not typically used for emotional or abstract reinforcement (like "strengthening a relationship"); other words would be more appropriate there.

Common Mistake

Avoid confusing "補強" with "補足" (ほそく), which means "supplement" or "additional information." "補強" implies strengthening or making something more robust, while "補足" is about adding missing parts or details.
