The "Friends" alum has said that the struggle comes from the fact that the term is used by people to call their same-gender lover in her hometown of Alabama, reports aceshowbiz.com.
"He's my partner, that's what he calls it, 'my partner'... I'm from Alabama, so you don't really say partner unless you're in the same sex... Saying partner is difficult for me," Cox told host Jimmy Kimmel.
She said the term has caused some confusion in the past.
"I was in Atlanta not that long ago and I was like, 'Oh, I'm supposed to meet my partner in section F,' and they were like, 'Oh, I'm sure she's going to be there, don't worry about it'," she laughed.
"Not that it matters, but it's just a different way to speak."
Back in October 2018, Cox coyly responded to a question about their marriage plan by saying that they were married "in her heart". McDaid also responded sweetly when he was asked what that meant. He said: "We have one every morning when we look at each other."
