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.
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 noun in The Etymologies of the 1930s glossed “surface, bosom, bosom of Earth, (Old English) folde” derived from the root ᴹ√PAL “wide (open)” (Ety/KEM). Here “folde” is an Old English word meaning “land, earth, ground”. The word “bosom” likewise in Old English could refer simply to a surface, and as an anatomical reference described the chest regardless of gender. Given these glosses, it seems unlikely that this word could be applied to the breasts of a woman, to which the term “bosom” was not applied in English until the 20th century.
