'Enyaach: "I", pronoun used optionally
'aalymam: First-person of 'elymam, "is small, little". Though the Campo word for "small, little" is provided as lymam by Adolf Thing in the Barona dictionary, Robertson says the word as 'elymam. Robertson's derivatives of 'elymam including 'aalymam "I am small" and ma'lymam "you are small" are consistent with 'Iipay rules for conjugating verbs that start with 'e-.
We know the subject of this sentence is "I" and not "the sun" (also 'enyaa) because the verb is conjugated in first-person and not third ('enyaach 'elymam "the sun is small").
