It stands for "predicate", such a function returns t or nil.

there is also the "f" suffix for "function", e.g. `cl-incf'
and `cl-decf' ... and a couple of other conventions I can't
remember right now.

Speaking of CL, the convention for *global-variables* is not
encouraged in Elisp.

Other than that do this

(require 'checkdoc)

(setq checkdoc-permit-comma-termination-flag t)

(defun check-package-style ()
  (interactive)
  (let ((msg "Style check..."))
    (message msg)
    (checkdoc-current-buffer t) ; TAKE-NOTES
    (message "%sdone" msg) ))
(defalias 'check-style #'check-package-style)

and do byte-compile for more pointers ...
