Correct spelling for the English word "bedirt" is [bɪdˈɜːt], [bɪdˈɜːt], [b_ɪ_d_ˈɜː_t] (IPA phonetic alphabet).
The word "bedirt" is a combination of the prefix "be-" and the word "dirt".
The prefix "be-" in Middle English was used to intensify or add a sense of completion to a verb or noun. In this case, it is used to intensify the meaning of "dirt".
The word "dirt" has Germanic origins, derived from the Old Norse word "drit" meaning excrement. Over time, it evolved to refer to any unwanted or soiling substance. The transition from "drit" to "dirt" happened through Middle English where it adopted the meaning of "unclean matter" or "filth".
When "be-" is added to "dirt", it results in "bedirt", which means to cover or soil with dirt.
