Can anybody help? Why does the form change with personal prononus, when we talk about he/she /it.
I've looked in Swan's Usage but can't find it.
he/she /it goes?
The same occurs when we use "do".
I/you/we/they do it but he she and it does it.
"The traffic causes conjestion".- It causes conjestion.
Does the traffic cause conjestion?
The verb changes and we drop the "s" in causes, when we form the question.
