Huai is a bilingual typeface which stands in between Thai script, Latin script, Thai Latinized and conventional. Most of the contemporary loop-less Thai typefaces obtained some Latin letterforms when crafting Thai alphabets. If Thai alphabets can borrow the form from Latin letterforms, what might happen when Latin alphabets are influenced by those original Thai letterforms? Huai Latin letterforms adopted the essence of Thai alphabets from the handwritten form, which was initiated by locals, and appeared in manual Ad signs. The proportion and writing system of Thai allowed Latin alphabets of Huai to reflect a sense of Thai letterforms. The Thai letterform of Huai not only remains the pioneer proportion and writing system, but it also allows the outcome of Huai Latin to be influenced, as well. In general, Thai fonts have two different terminal styles: the loop terminal and the loopless. Through the design-making process of Huai, Thai handwritten script was transformed to Latin, and then transformed back to the digital Thai typeface.
