Whether or not the child knows the concept underlying the word influences the ease with which the word is learnt. For example, most children will have experienced ‘exhaustion’ and will therefore find this word easier to learn than ‘gravity’, which is an abstract concept outside their personal experience. Not only will children have personal experiences to hook the word ‘exhaustion’ onto ,but teachers and caregivers will find this word easier to model and explain than ‘gravity’, as they will be able to relate it to the word ‘tiredness’ and role play being exhausted. Furthermore, words grounded in everyday experience are easier to repeatedly use for a range of authentic purposes.
