Sometimes here I've been taught that some form is "continuative". I read some webpages to try to understand what it means, but I'm not getting it. For example, this webpage
http://www.epochrypha.com/japanese/materials/verbs/teform.html
says the "te" form is a continuative form because "it forms a subordinate clause that requires a main clause for completion." What is the main clause this clause is subordinated when you use it as imperative? . That webpage also says the main clause can be implied but I dont see which one it could be in cases like Tabete kudasai.
