A verb translated “overshadow”, given as an example of a derived-verb (SD/439). It appears to contain the element ugru “shadow”, so perhaps the final element -dâ- is a causative verbal suffix.

A noun attested only in the compound agannâlô “death-shadow [is]” (SD/247, VT24/12). The first element of the compound, agan “death”, as identified elsewhere (SD/426), so the remaining element must mean “shadow”. The compound is the subject of the sentence agannâlô burôda nênud “death-shadow [is] heavy on us” and is therefore in the subjective case. According the grammatical rules of Lowdham’s Report, the only possibly normal form producing this subjective is nâlu: compare nîlu “moon” to its subjective form nîlô (SD/431).
Conceptual Development: In early writings, the compound was (non-subjective) agannūlo, so that the apparent draft form of this noun was nūlo. A similar form nūlu appears on SD/306, described only as “a word with the evil sense of ‘night’ or ‘dark’”. It could be a separate word or another variation of this word, with the development nūlo >> nūlu >> nālu. Carl Hostetter and Patrick Wynne suggested (AAD/21) that the earlier forms may be related to ᴹQ. nulla “dark, dusky, obscure”.
A noun translated “shadow” (SD/247), also described as “a word with the evil sense of ‘night’ or ‘dark’” (SD/306). It appears in the preprositional phrase ugru-dalad “under shadow” (SD/247) and in the draft-dative form ugrus “‽horror‽shadow” (SD/311).
