Нос is a masculine noun; the ending pattern above repeats across most masculine nouns, so every table you learn makes the next one cheaper. One extra form matters here: for location after в or на, Russian says в носу, with the stress on the ending, instead of the regular prepositional.

Look up any other word in the Russian declension tool, see where нос ranks in the most common Russian words, or start from Russian cases explained if the table above is new territory. More vocabulary lives in Russian words by topic and Russian phrases.

12 forms is a table. Using them is a skill.
