The word is made up of 'Ehe' (marriage) and 'Partner' (partner). So it literally describes a 'partner in marriage.'
Ihr Ehepartner hat sie am Bahnhof abgeholt.
Her spouse picked her up at the train station.
'Ehepartner' (spouse) is a neutral and rather formal term. It is often found in official documents, forms, and legal language.

'Der Ehepartner' (the spouse) is often used as a gender-neutral umbrella term for husband or wife. So a person can say 'mein Ehepartner' (my spouse), regardless of whether they are talking about their husband or wife.
Mein Ehepartner und ich teilen uns die Hausarbeit.
My spouse and I share the housework.
half
'die bessere Hälfte' (better half) and 'der Ehepartner' can both refer to the person someone is married to. The difference is mainly in tone. 'der Ehepartner' is neutral and precise; it is used, for example, in forms, at government offices, or in factual conversations. 'die bessere Hälfte' is informal and often humorous. It sounds more personal and relaxed. In official situations, 'Ehepartner' fits better; in everyday life, 'meine bessere Hälfte' (my better half) can sound friendly or joking.
