In the ‘Use of English’ section of the Cambridge First, Advanced and Proficiency exams, one of the tests involves ‘word building’.
I always advise my English language students to develop and extend the vocabulary they record in their notebooks. This could be by making extensive notes, or drawing diagrams such as a ‘word web’.
So, if they learn a new noun, I advise them to find any other parts of speech relating to that noun (e.g. verbs, positive and negative forms of the relevant adjectives, adverbs etc.).
I also advise my students to read as many English language texts as they can so they increase their familiarisation of vocabulary and can start to identify ‘root’ words.
