Use an online translator tool to translate English to Mayan. The perl script translator app devised by Jim Duyer is one example. Click in the box and type the text you want to have translated. Then click “Translate this.” The corresponding Mayan glyphs will be shown.
Use a dictionary, such as the Maya Hieroglyph Dictionary produced by Peter Mathews and Péter Bíró. Scroll down to “English Words.” Click the letter that your English word begins with. A list of words beginning with the chosen letter appears. The pronunciation is shown on the left. The hieroglyph is shown on the right. You can also use the “Word Search” tool to locate an English word, if present in the dictionary.
Discover more about how to translate Mayan with “A Preliminary Classic Maya - English / English - Classic Maya Vocabulary of Hieroglyphic Readings” written by Erik Boot of Leiden University in the Netherlands.
