What is the meaning of らと?

Question

I was reading this news article today:

阿部サダヲが4年ぶりの主演ドラマで水原希子、山口智子らと共演

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.

Answer 1

「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."

Answer 2

= 達と

水原希子、山口智子らと共演 → 水原希子、山口智子 & Others
