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?)
Quenya

elwen noun "heart" (LT1:255; rather hón or enda in LotR-style Quenya)
axo
bone
axo noun "bone"; pl. axor in Markirya
axo
noun. bone
A word for “bone” appearing in the Markirya poem from the 1960s in its plural form axor (MC/222-223). It might be related (conceptually if not etymologically) to the root √AKAS “neck, ridge” (PE17/92).
Conceptual Development: A similar word ᴱQ. as (ass-) bone dates all the way back to the Qenya Lexicon of the 1910s (QL/33). The locative plural of this noun assari “of bones” appeared in the Oilima Markirya poem written around 1930. The form ᴹQ. astŭ- “bone” appeared in the Declension of Nouns from the early 1930s (PE21/27).
Neo-Quenya: While this word could be derived from ✱aksō, I prefer to assume it is derived from ✱ᴺ✶askō with metathesis sk > ks in Quenya. This makes it more etymologically distinct from axë “neck” and also allows a (Neo) Sindarin form ᴺS. asg “bone”, since a Sindarin derivative of ✱aksō would collide with S. ach “neck”.
enda
heart
enda noun "heart", but not referring to the physical organ; it literally means "centre" (cf. endë) and refers to the fëa (soul) or sáma (mind) itself. (VT39:32)
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.
rama-
to shout
rama- vb. "to shout" (LT1:259)
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).
hollë
noun. shout
The word for the “heart” as a physical organ, as opposed to more metaphorical words like Q. órë and Q. indo. Its stem form was hom- in Tolkien’s later writings (NM/176, PE19/97).
Conceptual Development: The base word for “heart” was quite stable in Tolkien’s mind, but its exact stem form varied. It first appeared as ᴱQ. hon (hond-) “heart” in the Qenya Lexicon of the 1910s under the early root ᴱ√HONO, above a longer form hondo (QL/40). It became honde “heart” in Early Qenya Word-lists of the 1920s (PE16/137), but in the contemporaneous Early Noldorin Word-lists, it was londo (PE13/149, 162).
In the Declension of Nouns from the early 1930s it was ᴹQ. hón “heart” with stem form hom- (PE21/23), but in The Etymologies written around 1937 it was derived from the root ᴹ√KHŌ-N “heart (physical)” (Ety/KHŌ-N). In 1968 notes on gender, hón the “physical organ heart” again had a stem form hom-, and in green ink addendums to the Outline of Phonology (OP2) from around 1970, Tolkien gave the primitive form as ✶khō̆m (PE19/97 and 98 note #142). In this last note, Tolkien said it “is not the physical heart, but ‘the interior’ used of the whole range of emotions or feelings”; this seems to be the only place Tolkien indicated this word was metaphorical in nature rather than referring to the physical organ.
