Previous study related to booster expression is still limited to cross-cultural variation in the use of hedges and boosters in academic discourse (Dontcheva Navratilova, 2013;Salichah, Irawati, & Basthomi, 2015;Demir, 2017;Farnia & Mohammadi, 2018), promotional brochue (Ilham, Bulkani, & Darlan, 2018), research article (Sanjaya, 2013;Takimoto, 2015;Hryniuk , 2018;Aull, 2019) critical discourse analysis of in election debates of presidential candidates (Elhambakhsh & Masoome, 2015), patterns of metadiscourse (Kondowe, 2014;Hyland & Jiang, 2018), English newspaper editorial (Zarza, 2018;Al-Ghoweri & Al Kayed, 2019;Ahmad, Mahmood, Mahmood, & Siddique, 2019), gender (Shrivastava, 2016;Shakirova & Safina, 2019), and translation studies (Herriman, 2014;Martikainen, 2018;Ilham, Nababan, Kristina, & Wiratno, 2018). However, those studies focused on the use of boosters in academic discourse, direct communication, newspaper articles, gender, and do not yet discuss booster expression employed in speech act at literary works.…”
