 However, when we speak of loanwords we have in mind items of foreign origin that have become habitual elements of Nawat usage and may also have undergone adaptation as a result.With one possible exception ("pashalua" 'go for a walk, take time off work' < *pasyarua < Spanish "pasear" + the non-productive verb suffix "-ua"), verbs can only be borrowed into Nawat from other languages in an invariable form based on the Spanish infinitive.Such forms cannot be conjugated directly.
