The verb 'seilen' (to rope) is derived directly from the noun 'das Seil' (rope). The basic meaning is therefore to do something with a rope.
EXAMPLE

Use in compounds
The verb 'seilen' (to rope) is hardly used on its own anymore. You find it almost exclusively in separable verbs such as 'abseilen' (to rappel), 'anseilen' (to rope up), or 'aufseilen' (to hoist with a rope), which describe a specific action with a rope.
EXAMPLE
Die Bergsteiger seilten sich gegenseitig an, um nicht abzustürzen.

The reflexive form 'sich abseilen' has, in addition to its literal meaning (to lower oneself on a rope), a very common colloquial meaning: to slip away secretly or unnoticed.
EXAMPLE
Die Party war langweilig, also haben wir uns früh abgeseilt.

seilen vs sichern
to secure / save
'sichern' and 'seilen' can both have to do with a rope and protection from danger. 'sichern' is the normal and important word when you make someone or something safe, for example when climbing. 'seilen' means to connect or secure someone or something with a rope, but it is rarely used on its own. You hear forms like 'anseilen' (to rope up) or 'abseilen' (to rappel) much more often. Learners may confuse the words because a rope can be involved in both cases. In practice: when protection is the focus, you say 'sichern'. When it is about attaching or using a rope, a form with 'seilen' is usually suitable.
seilen
Vor dem Aufstieg seilen sich die Bergsteiger an.
