ढाई (dhaaii)

numeral A numeral meaning 'two and a half' -- an irregular word that does not follow the pattern of ordinary numbers combined with आधा (aadhaa, 'half').
Sense 1 : two and a half
numeral Used directly before a noun (often in its counted/oblique form where relevant), e.g. ढाई घंटे (dhaaii ghante, 'two and a half hours'), ढाई किलो (dhaaii kilo, 'two and a half kilos').
Frequency: high
Cultural Note: Hindi has unique, irregular words for 'one and a half' (डेढ़, dedh) and 'two and a half' (ढाई, dhaaii); from 'three and a half' onward, the regular pattern साढ़े + number (saadhe) kicks in, e.g. साढ़े तीन (saadhe tiin, 'three and a half'). You will hear ढाई (dhaaii) constantly in everyday contexts -- prices, time, distances, ages -- so it is well worth memorizing as a standalone word rather than trying to derive it.
Common Mistakes: 1) Learners often try to build this compositionally as दो और आधा (do aur aadhaa) or दो-आधा (do-aadhaa); Hindi instead uses the single irregular word ढाई (dhaaii), just as साढ़े तीन (saadhe tiin) is used for 'three and a half' rather than a similar compositional form. 2) Note that 'one and a half' is not बनाया from this pattern either -- it is डेढ़ (dedh), another irregular form, so ढाई (dhaaii) should not be assumed to generalize downward.
