Is there a name for 2-character "in-between" words in which both characters are abbreviations for individual 2-character words? As I improve my vocabulary, I'm encountering a lot of "in-between words": they are 2-character words where both characters are both contractions of individual 2-character words.  I don't know if these words have a name.

Question: Is there a name for 2-character "in-between" words in which both characters are abbreviations for individual 2-character words?

To give an idea of what I'm referring to:


舒适 seems to combine 舒服 and 合适;
谢绝 seems to combine 感谢 and 拒绝;
互动 seems to combine 互相 and 活动;
短暂 seems to combine 短期 and 暂时;
节庆 seems to combine 节日 and 庆祝;
损害 seems to combine 损失 and 伤害.


I'm not sure if all these particular examples are exactly correct, but hopefully you get the overall idea.  (Please ensure answers actually answer the question, and not just comment on the examples.)
Two characters words are all compound words. There are different ways to coin compound words
One way to coin compound word is to combine two characters that share a similar meaning to make it specific
Most single character words contain multiple meanings thus make them too general for expressing a more specific meaning.
Example (adj + adj) :

沉 can mean 'sing' or 'heavy'
To make a specific term, we add one more character to it to clarify the meaning
没 also have the meaning of 'sink', That make '沉没'  specifically  mean 'sink'
重 also have the meaning of 'heavy' That make, '沉重' specifically  mean 'heavy'

Example (verb + verb) :

攻 means 'attack' but it also contains the meaning of: study; specialize in; work at
擊 mainly mean 'hit' but it also contains the meaning of: 'attack'
攻擊 is a specific term for 'attack'

攻擊 are not abbreviations for 攻打 and 打擊

攻擊,  攻打 and 打擊 are all compound words that happen to share one component (攻擊 and 攻打 share 攻; 攻打 and 打擊 share 打)


Example from this post 认识 vs 知道 based on glyph origins

見識: experience(v) = (see + know) *'to see to know'
見識: experience(n)= (see + knowledge) knowledge from what you had seen
學識: knowledge; acquirements (n) = (learn/study + know) knowledge from what you had studied
常識: common sense; general knowledge(n) = (common + knowledge) knowledge that is common

They are all compound words that share the 識 component
It doesn't mean 見識 are abbreviations of 眼見/看見 and 認識/知識
It doesn't mean 常識 are abbreviations of 平常/通常 and 認識/知識
