延

Long-stride radical 廴 with an extra inner stroke — picturing a leg taking a stretched step. It is the indexing radical and supplies the core meaning of 延: motion drawn out across distance or time, giving rise to 'extend, prolong, postpone' and to relatives like 廷 (court), 建 (build), 廻 (return).

Lone left-falling stroke perched on top — visually marking the head of a stretched-out figure. It is not a meaningful component on its own; it caps the long-stride radical below, helping the parent character look like a person reaching forward in mid-step.
