Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
The root ᴱ√SṆTṆ “esteem” appeared in the Qenya Lexicon of the 1910s with derivatives ᴱQ. santa “dear, beloved” and ᴱQ. sinte “esteem; estimate, computation” (QL/85). There are no signs of this root in Tolkien’s later writing, but I think it is worth positing a Neo-Root ᴺ√SINIT for “esteem” and “estimate” words.
