Does English have a word for 师兄/师弟/师姐/师妹？ I know one obvious translation would be &quot;classmate.&quot; However, I have also heard the above words used when two people have had the same teacher. For example, if someone had the same teacher as you ten years ago, he is your 师兄. Since you two were never in fact classmates, is there a more precise translation than &quot;classmate&quot;?
I don't think there is a translation into standard English.
In some regional dialects (India, Singapore, maybe some other places) you hear people using the words &quot;junior&quot; and &quot;senior&quot;, which roughly mean &quot;person who goes/went to the same school of a lower/higher year&quot;.  E.g. &quot;she is my senior&quot;.
In very informal situations you can use the Japanese loanwords senpai and kohai which have the same meaning.
&quot;Classmate&quot; is not a good translation as it doesn't have the junior/senior connotation.
junior/senior/senpai/kohai are probably the closest direct translations.
