There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
skar
root. tear, rend
skar
root. ?stop, end; limit, marge
A hastily written entry in The Etymologies of the 1930s with an unclear gloss (possibly “stop, end; limit, marge”) serving as the basis for the name Ilk. Esgaroth (also with an unclear gloss, possibly “?strand-burg”) with the element Ilk. esgar = “shore” (EtyAC/SKAR²). The name Ilk. Esgaroth was given a much clearer etymology as “Reedlake” under the entry ᴹ√ESEK “✱sedge, reed” (Ety/ESEK).
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A root in The Etymologies of the 1930s glossed “tear, rend” with derivatives like ᴹQ. harna-/N. parch “to wound” and ᴹQ. harwe/N. harw “wound” (Ety/SKAR).
