Is the construction 连A带B meaning "both A and B" a general construction or limited to fixed expressions? The Pleco dictionary mentions the construction 连A带B meaning &quot;both A and B&quot; in the definition of 连, but I can't find any other discussion of this structure.
I see it in fixed expressions like 连滚带爬 (lit &quot;both rolling and crawling&quot;, but figuratively &quot;frantically trying to escape&quot;) and 连踢带打 (lit &quot;to kick and hit&quot;).

Can it be used to link anything together, or is it only used in fixed expressions?
In fixed expressions A and B are both verbs. Does it only work for verbs?
I've found what appear to be examples of 连A带B带C to connect 3 things together. Does it work for as many things as you want?
Does it add any emphasis or other flavor to A+B? Simultaneity? Intensity?

连消带打, 连哄带骗 and 连滚带爬 are considered fixed expressions because they are commonly spoken in day-to-day speech.
But A and B in [连 noun A 带 noun B] can be anything related or not

The common structure is (连)A(带)B(与及/外加/再加上)C. e.g. 连人带马与及军旗一起翻落山坡; 连店带货再加上招牌一起顶让给别人; 連哄帶騙外加小許威迫

连A带B indicates 'also' or 'both'.

verb A and verb B happen at the same time or alternately.

noun A and noun B are both the objects
