married couple; husband and wife
Refers to a married pair as a unit. Neutral and widely used in daily conversation, official documents, and media.
That married couple always gets along well.
Traveling as a couple is our hobby.
After a long relationship, the two of them finally became husband and wife.
Every year, my spouse and I look forward to going to a hot spring together.
