[[Language]] functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right-handed individuals.<ref name="Taylor">{{cite book | vauthors = Taylor I, Taylor MM | year = 1990 | title = Psycholinguistics: Learning and using Language | publisher = Pearson | isbn = 978-0-13-733817-7}} p. 367</ref> While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers.<ref name="Beaumont">{{cite book | vauthors = Beaumont JG | year = 2008 | title = Introduction to Neuropsychology | edition = Second | publisher = The Guilford Press | isbn = 978-1-59385-068-5 | chapter = Chapter 7 }}</ref> This is particularly important when it comes to writing, a form of language that involves hand use. Studies attempting to isolate the linguistic component of written language in terms of brain lateralization could not provide enough evidence of a difference in the relative activation of the brain hemispheres between left-handed and right-handed adults <ref>{{cite journal | vauthors = Papadopoulou AK, Samsouris C, Vlachos F, Badcock N, Phylactou P, Papadatou-Pastou | title = Exploring cerebral laterality of writing and the relationship to handedness: a functional transcranial Doppler ultrasound investigation | journal = Laterality | volume = 29 | issue = 1 | pages = 117–150 | date = November 2023 | doi = 10.1080/1357650X.2023.2284407| pmid = 38112692 }}</ref>
