आलसी (aalsii)

adjective A single-sense word meaning 'lazy' -- describes a person's habitual disposition rather than a one-off action.
Sense 1 : lazy, indolent
adjective
Synonyms: सुस्त (sust), निकम्मा (nikammaa, colloquial)
Frequency: high
Cultural Note: A Delhi mother scolding a child who won't get out of bed on a winter morning will almost certainly reach for आलसी (aalsii) -- 'कितना आलसी है तू!' (kitnaa aalsii hai too, 'how lazy you are!') is a classic household line. It pairs naturally with the noun आलस (aalas), which describes the feeling of laziness/lethargy itself rather than the trait of being lazy.
Common Mistakes: 1) Learners sometimes try to inflect it like a regular -आ adjective (e.g. आलसा (aalsaa) for masculine, आलसी (aalsii) for feminine) -- but आलसी (aalsii) stays the same form for both genders and for singular and plural, since it ends in the invariant -ई (ii) pattern, not the variable -आ (aa) pattern. 2) Don't confuse with आलस (aalas), the related noun meaning 'laziness' -- आलसी (aalsii) is the person-describing adjective, आलस (aalas) is the abstract quality itself, as in मुझे आलस आ रहा है (mujhe aalas aa rahaa hai, 'I'm feeling lazy/lethargic').
