Time words like ‘yesterday' and ‘tomorrow' are abstract, and are interpreted relative to the context in which they are produced: the word ‘tomorrow' refers to a different point in time now than in 24 hours. We tested 112 3- to 5-year-old Hindi-speaking children on their knowledge of ‘yesterday' and ‘tomorrow', which are represented by the same word in Hindi-Urdu: ‘kal'. We found that Hindi learners performed better than English learners when tested on actual past and future events, but that performance for hypothetical events was poor for both groups. Compatible with a “syntactic bootstrapping” account, we conclude that syntactic tense information – which is necessary for differentiating ‘yesterday' from ‘tomorrow' in Hindi – may play a stronger role in learning these words than mapping of specific words to particular past and future events (“event mapping”).
