Help one gets in this day and age (3)

Ross

I believe the answer is:

aid

I'm a little stuck... Click here to teach me more about this clue!

'help' is the definition.
(synonyms)

'one gets in this day and age' is the wordplay.
'one' becomes 'i' (Roman numeral).
'gets in' is an insertion indicator.
'this day and age' becomes 'ad' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'i' inserted within 'ad' is 'AID'.

Can you help me to learn more?

(Other definitions for aid that I've seen before include "Good point" , "Auxiliary" , "charity" , "Help, assistance" , "encouragement" .)

I've seen this clue in The Guardian and The Globe and Mail.
