This should help lead you down a different path I think...
'Slemareld' for 'Silmarils', for example, appears to show that you are reading some vowel diacritics in a different order, and your -ld here perhaps confuses lambe plus s-hook
as used in representing Quenya (a following s can be indicated by a hook extending downward). The variation of i and e aside, lambe
plus 's-hook' helps your 'taldi' as well.
There are shorthand forms used for English 'the, of the,' for example, which I think are also throwing you a bit here.
