Ling is Old English for heather and may be an alternative toponymological derivation.

A number of different alternative derivations have been proposed in order to overcome this problem.

In recent years, alternative derivations of the SEA equations based on wave approaches have become available.

A suggested alternative derivation was *meh "to measure" (Gray 1929).

An alternative derivation may be an old hill-name of Celtic origin.

An alternative derivation produces an equation similar in appearance, but with V on the left-hand side.

An alternative derivation is from a Celtic name, meaning fort of refuge.

An alternative derivation simply refers to slippery or boggy ground; again, a typical habitat for this plant.

An alternative derivation for the name is a corruption of "seaman's sight", because the hills are visible from the North Sea.
