hón
heart
hón noun "heart" (physical) (KHŌ-N); hon-maren "heart of the house", a fire (LR:63, 73; this is "Qenya" with genitive in -en, not -o as in LotR-style Quenya read *hon-maro?)
indo
heart, mood
indo (1) noun "heart, mood" (ID), "state" (perhaps especially state of mind, given the other glosses) (VT39:23), "mind, region/range of thought, mood" (PE17:155, 179), "inner thought, in fea as exhibited in character or [?personality]" (PE17:189). In another post-LotR source, indo is translated "resolve" or "will", the state of mind leading directly to action (VT41:13). Indo is thus "the mind in its purposing faculty, the will" (VT41:17). Indo-ninya,a word occurring in Fíriels Song, translated "my heart" (see ninya). In the compound indemma "mind-picture", the first element would seem to be indo.
órë
heart
órë (1) noun "heart" (inner mind), also name of tengwa #21 (Appendix E), "premonition" (VT41:13), "nearest equivalent of 'heart' in our application to feelings, or emotions (courage, fear, hope, pity, etc.)" (VT41:13). The órë apparently defines a person's personality, cf. the description of Galadriel in PM:337, that "there dwelt in her the noble and generous spirit (órë) of the Vanyar". Órenya "my heart" (VT41:11).
elwen noun "heart" (LT1:255; rather hón or enda in LotR-style Quenya)
