Third-person narration locked tight to one character's perceptions, thoughts, and voice.
Close third (or deep third) keeps the 'he/she/they' pronouns of third person but presses the lens right up against a single character, filtering everything through their perceptions, word choice, and biases without the quotation marks of first person. It buys intimacy while keeping a sliver of authorial distance.
The discipline is staying inside that one head for the length of a scene: no fact the viewpoint character couldn't know, no jump into someone else's thoughts. Slipping that boundary is head-hopping, and it quietly drains the intimacy close third exists to create.
