  A pseudo-Nambu Goldstone Boson (pNGB) arising from the breaking of a global
symmetry ($G\rightarrow H$) can be one of the most promising candidates for the
quintessence model, to explain the late-time acceleration of our universe.
Motivated from the Composite Higgs scenario, we have investigated the case
where the pNGB associated with $SO(N)/ SO(N-1)$ develops a potential through
its couplings with the particles that do not form the complete representations
of $G$. The Coleman Weinberg (CW) potential is generated via the external
particles in the loop which are linked with the strongly interacting dynamics
and can be computed predicatively. The model of Dark Energy (DE) is tested
against several latest cosmological observations such as supernovae data of
Pantheon, Baryon Acoustic Oscillation (BAO), Redshift-space distortion (RSD)
data, etc. We have found that the fit prefers the sub-Planckian value of the
pNGB field decay constant. Moreover, we have found that the model predicts
cosmological parameters well within the allowed range of the observation and
thus gives a well-motivated model of quintessence.
