I have been reading articles by various sources, and they seem to interchangeably call the U1/U2/U4/U6 compounds involved in RNA splicing snRNPs as well as snRNAs.

This confuses me deeply. They must only be one or the other, no? Thank you in advance!

snRNA: small nuclear ribonucleic acid

snRNP: small nuclear ribonucleoprotein

snRNA refers to the RNA itself. snRNP refers to snRNA complexed with some protein(s). You could call spliceosomal RNA either depending on the context.

Most small and large RNAs typically exist and function in complex with proteins as ribonucleoprotein particles so the second denomination is more appropriate.
