Are there any sentences where if you skip one (or more) characters from the beginning, it's correct but has entirely different meaning?
How about these:

"(國人)對大麻合化意見不 一" -- "(Citizens of this country) have different opinions on the legalization of marijuana"

~

"(德意志)崩潰" -- "(German) collapse"

"(意志)崩潰" -- "(will/ spirit) collapse"

~

"(從)[馬上]下來" -- "come down (from) [the horse back]"

"[馬上] 下來" -- "come down [immediately]"

~

"(從來就)有免費飯" -- "There's (always been) free meal"

"(來)[就]有免費飯" -- "There's free meal [whenever] you (come)"
