The mass of the recently discovered charm tetraquark state has been estimated in the framework of the diquark–antidiquark 
and in the di-hadronic states approach. In the context of the effective mass approximation, diquarks have been designated as quasiparticles and have been used to study the tetraquark state. It has also been investigated considering it as a di-hadronic state of di-
mesons. The results have been compared with the experimental value and other theoretical works. It is observed that the mass of the tetraquark state in the diquark–antidiquark configuration shows very good agreement with the experimental results. The diquark–antidiquark picture in the context of the effective mass approximation seems to describe the system very well.
