Definition:
Getting is a verb which is primarily used to express some form of motion - whether physical movement or other forms of transition.
Rules:
Getting is most commonly used in the present continuous tense (eg. 'He is getting better'), which expresses the continuous state of being at a certain time.
Examples:
'She's getting ready for the show.'
'I am getting better after last match.'
Tips:
Getting is often used with certain infinitives and participles, and can sometimes become confused with other versions of 'get' (such as 'gotta') due to colloquial speech. Additionally, it is important to note the differences between 'getting' and the verb 'to be' - while 'getting' implies motion, 'to be' expresses staying in a certain state.
