For example, if the word ‫>أكتب‬ />ktb /Write in MSA is preceded by a negative particle such as ‫/لم‬lam (Do not), the verb in the dialect will be: mAktibti$/‫=ماكتبتش‬ TUN-Neg-Particle(‫+)ما‬ Tun-verb ‫+)كتب(‬ Tun-Neg-enc ‫)ش(‬ Tools words or Syntactic tools exist in a large amount in the Treebank and all MSA-texts.
their transformation was not trivial and required for each tool a study of its different contexts.
