The Adûnaic number “two” (SD/428). It seems likely that it is related to Q. atta “two”, as suggested by Carl Hostetter and Patrick Wynne (AAD/22), though it is unclear how the initial s- might have developed in the Adûnaic. It may also be related to the Adûnaic dual suffix -at, as suggested by Andreas Moehn (EotAL/SAT).

A noun translated “sun” (SD/306, 428). This word appears in the forms ûrê, ûri and ûrî, but Tolkien declared that the form with long î is actually the personified form Ûrî “Lady of the Sun” (SD/426), perhaps the Adûnaic name of Q. Arien. The form ûrê only appears once (SD/426), so ûri is probably to be preferred as the ordinary word for Sun, especially since it is a neuter noun, which ordinarily cannot end in a long -ê (SD/427). Tolkien lists the “later forms Uir, Ŷr” (SD/306), one of which may be the Westron word for “sun”, most likely Wes. uir. As suggested by several authors (AAD/24, EotAL/UR), ûri is probably derived from the Elvish root ᴹ√UR.
The inflection used to put neuter nouns into the subjective case (SD/430), used either as a suffix (for weak-nouns) or augmenting the last vowel (for strong-nouns). See the entry on the subjective case for further details.
