Okay, so I tried with these

(defun spell-word-2 (word)
  (and (ispell-lookup-words word) t) )
;; (spell-word-2 "length") ; t
;; (spell-word-2 "lenght") ; nil

(defun spell-word (word)
  (with-temp-buffer
    (save-excursion
      (insert word) )
    (condition-case nil
        (not (ispell-word))
      (error nil) )))
;; (spell-word "length") ; t
;; (spell-word "lenght") ; nil

Maybe spell-word-2, using `ispell-lookup-words', is faster as
you say, but something is different because with the
permutation use case and code previously discussed [1] this

  (string-perms-filter "pigelsen")

only returns "sleeping". With my old spell-word both are
returned, i.e. ("peelings" "sleeping") - no idea why actually,
I'll leave it to my subconscious to figure out God willing ...
