  We present the analysis of the optical variability of the early,
nitrogen-rich Wolf-Rayet (WR) star WR7. The analysis of multi-sector Transiting
Exoplanet Survey Satellite (TESS) light curves and high-resolution
spectroscopic observations confirm multi-periodic variability that is modulated
on time-scales of years. We detect a dominant period of $2.6433 \pm 0.0005$ d
in the TESS sectors 33 and 34 light curves in addition to the previously
reported high-frequency features from sector 7. We discuss the plausible
mechanisms that may be responsible for such variability in WR7, including
pulsations, binarity, co-rotating interacting regions (CIRs) and clumpy winds.
Given the lack of strong evidence for the presence of a stellar or compact
companion, we suggest that WR7 may pulsate in quasi-coherent modes in addition
to wind variability likely caused by CIRs on top of stochastic low-frequency
variability. WR7 is certainly a worthy target for future monitoring in both
spectroscopy and photometry to sample both the short ($\lesssim 1$ d) and long
($\gtrsim 1000$ d) variability time scales.
