I've read that this is one of the meaning that define a lepton and I was curious to see what this means. Other resources aren't being very clear.

To answer this, it would indeed require some very theoretical background and mathematics. It's not easy to give such an answer on B level without using a technical language. This is likely the reason your sources haven't been very clear on this. @ChrisVer's answers already gave you a short glimpse.Irfan Nafi said:I've read that this is one of the meaning that define a lepton and I was curious to see what this means.

Spin is a fundamental property of subatomic particles, such as electrons and protons, that describes their intrinsic angular momentum. It is a quantum mechanical quantity that is always measured in units of half-integer or integer values.
Half-integer spin means that the spin of a particle is a half-integer multiple of the reduced Planck constant (h-bar). This includes particles like electrons, which have a spin of 1/2, and particles like protons and neutrons, which have a spin of 1/2 or 3/2.
Half-integer spin is important because it is a fundamental property of matter that is responsible for many of the observed behaviors of subatomic particles. It is also intimately connected to the Pauli exclusion principle, which states that no two particles with the same spin can occupy the same quantum state.
Half-integer spin is measured using a variety of techniques, such as electron spin resonance (ESR) and nuclear magnetic resonance (NMR). These methods rely on the interaction between the spin of a particle and a magnetic field, which can be detected and measured.
Yes, particles can have spin values other than half-integer, such as integer values like 0, 1, and 2. These particles are known as bosons and have different properties and behaviors compared to particles with half-integer spin, known as fermions.
