[tlhIngan Hol] Difference between {rIp} and {yej}

[mayqel qunen'oS]

De'vID:

What I'm wondering about, isn't whether I could rename the {quprIp} to
{qupyej}, or the {yejquv} to {rIpquv}.

I'm wondering whether I can use on their own and interchangeably the
{rIp} and {yej}.

Example:

vIghro' tIQ wIje' 'e' bot rIp
the council/assembly prohibited us bying an ancient cat

vIghro' tIQ wIje' 'e' bot yej
the council/assembly prohibited us bying an ancient cat

1st question:
Can I use {rIp} and {yej} in this way ? (i.e. on their own; not being
a part of a composite noun)

2nd question:
Do both of the above sentences mean the same ?
