“…The influence factors on Code-Switching (CS) as in (1–3) and on Language Choice of Bilinguals (LCB) as in (4) and (5) have been investigated from various perspectives, such as the structural ( Poplack, 1980 ; Cook, 1991 ; Myers-Scotton, 2002 ), social ( Schweda, 1980 ; Poplack, 1985 ; Fishman, 2000 ; Bullock and Toribio, 2009 ; Gardner-Chloros, 2009 ; Holmes and Wilson, 2013 ; Valenti, 2014 ), cognitive ( Müller, 2017 ; Kremin et al, 2021 , among others), and discourse perspectives ( Gumperz and Dell, 1972 ; Konidaris, 2004 ; Auer, 2007 ; Auer and Eastman, 2010 ). One important factor influencing CS and LCB is the relative size of speech communities ( Schweda, 1980 ; Poplack, 1985 ), alongside other factors such as age, addressee, topic of discussion, and language attitude (see Berisso Genemo, 2022 for various factors).…”
