Learn Swedish: Vi ser det inte i endera halvleken. - We do not see it in either half.

endera specifically means 'either of the two'. Because a sports game always has exactly two halves, endera emphasizes that we are talking about two specific options. någon would be used if there were three or more options.

Why is halvleken in the definite form (the half) instead of the indefinite form?

When used as determiners describing a noun, the formal dual words endera, vardera, and ingendera require the noun to be in the definite form in Swedish. That is why it is endera halvleken (literally 'either the half'), unlike English which uses the indefinite 'either half'.

Could we use ingendera (neither) instead of inte ... endera (not ... either)?

Yes, you could say Vi ser det i ingendera halvleken. Both mean the exact same thing. However, keeping the negation inte near the verb and using endera later in the sentence often feels a bit more natural and conversational in Swedish, much like choosing 'We do not see it in either half' over 'We see it in neither half'.
