Why tiring, not tiresome?

[Aranthaa]

Hi, Alan,

I don't understand why tiresome will not fit in here? When can I use this word?

Regards,
Elena

Hi,

Thanks for your question. Here in this test you need 'tiring' because it's a synonym for 'exhausting' in other words 'tiring' means 'making you feel tired'. Keeping young children happy during the school summer holidays is a tiring experience for parents. 'Tiresome' on the other hand means 'irritating'. For example my surname is TOWNEND but most people spell it wrong and say or write 'TOWNSEND' and for me that is tiresome or irritating.
