Please give us a description of what happened.

Indonesian has words with prefix and prefix+suffix, which in general have the same meaning with it's root word. But there are certain prefixes and prefix+suffix that give different meanings from it's root words Thus, yoast give incorrect results in its focus keyword calculations.

Please describe what you expected to happen and why.

Please exclude Prefix PE/PEN/PENG/PEM/PENY and Prefix PER with Suffix AN from it's roots words meaning, because the meaning is not same and very different.

Prefix PE/PEN/PENG/PEM/PENY (pe/pen/peng/pem/peny + root words) always give different meaning with it's root words.

Example: Main (Play) is different with Pe-main (Player) Curi (Steal) is different with Pen-curi (thief) Acara (event, program) is different with Peng-acara (lawyer) Kemudi (Streering Wheel) is different with Peng-emudi (Driver) Bentuk (Shape) is different with Pem-bentuk (Framer or Maker) Sakit (Sick) is different with Peny-akit (Disease)

Prefix PER with Suffix AN (per+root words+an) most of the time have different meaning with it's root words.

Example: jodoh (match, mate) is different with per-jodoh-an (matchmaking) guru (teacher, instructor) is different with per-guru-an (institution, school) bendahara (treasurer, chamberlain) is different with per-bendahara-an (treasury, repertory, exchequer) anak (child, kid) is different with per-anak-an (crossbreed, hybrid, half-breed) coba (try) is different with per-coba-an (trial, test, attempt) ingat (remember) is different with per-ingat-an (warning, memorial) izin (license, permission, consent) is different with per-izin-an (licensing)

How can we reproduce this behavior?

1. Put words with prefix above in articles.
2. Put root words as focus keyword
3. Check keyword density.
