This word is a simple compound of 'der Finger' (finger) and 'die Spitze' (tip/point). So it literally describes the tip of a finger.

I cut my fingertip with the knife.
In the literal meaning, 'Fingerspitze' (fingertip) is often used with verbs of feeling and touching, for example 'etwas mit den Fingerspitzen spüren' (to feel something with one’s fingertips) or 'jemanden berühren' (to touch someone).
Sie berührte sanft mit den Fingerspitzen seine Hand.
She gently touched his hand with her fingertips.
The expression 'etwas in den Fingerspitzen haben' means to have a very good feel for something. The thing that one is good at or senses well is in the accusative.

A good cook simply has a feel for the right spices.

'die Spitze' and 'die Fingerspitze' both refer to a front or outermost end. 'die Spitze' is general and can belong to many things, such as a knife, a pencil, or a tower. 'die Fingerspitze' is much more specific: it means only the sensitive end of a finger. The words can be confused because 'Fingerspitze' contains the word 'Spitze'. When you really mean the finger, 'die Fingerspitze' is the more natural and precise choice.

Mehmet berührte die heiße Tasse nur mit der Fingerspitze.
Mehmet touched the hot cup only with his fingertip.
Die Spitze des Bleistifts ist abgebrochen, deshalb kann ich nicht gut schreiben.
