Why “onehead” is a great word

ONEHEAD — [Noun] The state or quality of being one; oneness, unity, or solitude. From Middle English onehede, onhed, anhede, from Old English *ānhǣdu ("oneness, unity"), equivalent to one + the suffix -head (denoting state or condition). Unlike unity, which implies a harmonious joining of distinct elements, or solitude, which emphasizes an experiential aloneness, onehead denotes the fundamental, abstract fact of singularity. It is the indivisible point before a line begins, the unbroken surface of a still pond, the single candle flame holding its own shape in the dark—the irreducible condition of being a self-contained whole.

noun

Oneness; unity.
Solitude.
