Tetra = 4

Kis = copies of the same thing

Triphenyl = 3 phenyl groups (the rings) attached to the same atom (Phosphorus)

Phosphine = 3 R groups (molecule fragments like phenyl, methyl (CH3) etc) attached to Phosphorus

So there are 4 triphenylphosphine ligands attached to Palladium. Each triphenylphosphine has 3 phenyl groups attached to the same Phosphorus. Phenyl groups are basically rings of Carbon with all but one of the 6 Carbons attached to Hydrogen. The remaining Carbon is what attaches to the Phosphorus
