"How the hell can the dictionaries and encyclopedias not list it any longer?"

Most or all philosophical dictionaries list the neutral sense as the first or only definition.

Azkue's dictionary alone, which was printed in 1905, lists more than 80 Basque varieties of apples.

Likewise, several dictionaries now list a newer spelling Vaŝintono for Washington.

Consequently, most dictionaries will not list it as a separate word, and it is almost invariably ignored in collation.

Many dictionaries of word origins list these words as synonyms or as words with very similar meanings.

Consequently, Budge's 2-volume dictionary lists the sky hieroglyph under "pe-t"

(naming dictionaries typically list it as meaning "magnificent"), or with the sacred drink Haoma.

Most dictionaries list it as "nonstandard" or "incorrect".

Some recent dictionaries, such as the Reta Vortaro, no longer even list initial ŭ in their index.
