So, in other words, the meaning of  减 and 弱 are cumulative in this case and modify the same target?

<p>It may help if you analyze 减弱 in terms of a verb plus an adjectival complement of result, i.e. the subject NP reduces, with the result that it is weak.</p>

<p>I believe this word uses the &quot;coordinate&quot; compounding structure.

<p>It seems like 减弱 should mean &quot;reduce weakness&quot; and therefore &quot;strengthen&quot;, but it means the opposite.  For comparison, <a href="https://www.mdbg.net/chinese/dictionary?wdqb=%E5%87%8F%E8%82%A5" rel="nofollow noreferrer">减肥</a> means &quot;lose weight&quot;.</p>

I wondered the same thing myself quite recently, but then I decided to accept it as "just being that way". I think as students we come across 减肥 first, and then expect 减 to behave in the same way with other characters. Clearly it does not!

In "减肥", "肥" is the target and 减 is the action.

However in "减弱"， this is a verb as a whole, 弱 is NOT the TARGET。 When you say "强度减弱"，强度 is the target, 减 is the action, and 弱 is the result/status after the action. It literally means "减 something and 使 something 弱" (don't speak this way).

A similar example is its antonym "增强"。强 is the status after the action 增, rather than the target being 增ed. E.g. In "增强实力", 实力 is the target, 增 is the action, and 强 is the result/status after the action. Again, "增强" is a verb as a whole, don't separate them.

肥 in 减肥 is a noun; 弱 in 减弱 is an adjective

减肥 = 减(少)肥(胖) = reduce obesity

减弱 = 减(低)(變)弱 decrease and weaken

Example:

"颱風减弱" = "**颱風**(威力)**减**(低)(變)**弱**" = "Typhoon (power) decreases and weakens"

*The power decreased and the typhoon became weaker*
