[Grammar] a series of squares drawn on the ground

[Oceanlike]

In the sentence below, I don’t understand why the past participle ‘drawn’ is used. Please help me to understand why ‘drawn’ is correct.

Hopscotch is a game in which one or more players hop over a series of squares drawn on the ground.

Thank you! :-D

"...a series of squares that are drawn on the ground."

Hi,

I agree that the words that are are omitted. It follows then that the construction is are drawn, which is the passive voice, made up of the verb 'to be' (in the relevant tense) plus the past participle. Who did the 'drawing' (the 'agent') is not mentioned because in this instance it was apparently not important, but sometimes the agent is mentioned and usually follows 'by'. For example, 'This house was built by my father.'

I hope this is helpful.

Sue

Or "that have been drawn."
