I was reading this news article today:
In the heading and again in the text is 「山口智子らと共演」
My question is what is the meaning of the らと between Yamaguchi Tomoko and co-starring? I could not find any dictionary reference for it.
「らと」 is two words, not one, which is why it will not be found in the dictionary.
「～～ら」 = "~~, etc."
「と」 = "with"
"Sadao Abe is co-starring with Kiko Mizuhara, Tomoko Yamaguchi, etc."
