This question already has an answer here:

I will bring forward examples coming from my field of studies. For long time I have been wondering whether there are rationales or regional variances applied to the usage of dichotomies like:
pathologic/pathological;
neurologic/neurological;
anatomic/anatomical;
cytologic/cytological;
biologic/biological ; and so on and so forth.

I recall reading that "Anatomical pathology" is the name the discipline is given in the Commonwealth, compared with US "Anatomic pathology". But as for usage in their fields, all the listed terms seem to be a mixed bag (with google trends reporting different ratios, but always important numbers for each variant).

I hope someone will be able yo help me clear out this mess, either with practical rules or contextual examples
