Revision and meeting the cases

Let us recall spelling rules. A consonant that sounds voiceless at the end is checked by adding a vowel: kitob – kitobi. The apostrophe sign stands for no sound: ma’no, san’at. When the same consonants stand side by side, both are written: ikki. Word meanings: synonym, antonym, homonym. Word structure: base, word-forming and linking suffixes, possessive suffix.
