I was looking in DD's reading record last night (yr1) and her teaching assistant had been listening to her read, and had written "DD is now understanding words and there meanings".
No, it's "their".
I know I am a spelling/grammar Nazi but surely this is basic? For a TA to make that error I was a bit perturbed. Am I overreacting? I haven't mentioned it but a colleague at work suggested I correct the spelling in red pen
