fix) Stress and final glottal stop Stress is a distinctive feature in Tagalog. Primary stress occurs on either the final or the penultimate syllable of a word. Vowel lengthening accompanies primary or secondary stress except when stress occurs at the end of a word. Tagalog words are often distinguished from one another by the position of the stress and/or the presence of a final glottal stop. In formal or academic settings, stress placement and the glottal stop are indicated by a diacritic (tuldík) above the final vowel. The penultimate primary stress position (malumay) is the default stress type and so is left unwritten except in dictionaries. Grammar Writing system Tagalog, like other Philippines languages today, is written using the Latin alphabet. Prior to the arrival of the Spanish in 1521 and the beginning of their colonization in 1565, Tagalog was written in an abugida—or alphasyllabary—called Baybayin. This system of writing gradually gave way to the use and propagation of the Latin alphabet as introduced by the Spanish. As the Spanish began to record and create grammars and dictionaries for the various languages of the Philippine archipelago, they adopted systems of writing closely following the orthographic customs of the Spanish language and were refined over the years. Until the first half of the 20th century, most Philippine languages were widely written in a variety of ways based on Spanish orthography. In the late 19th century, a number of educated Filipinos began proposing for revising the spelling system used for Tagalog at the time. In 1884, Filipino doctor and student of languages Trinidad Pardo de Tavera published his study on the ancient Tagalog script Contribucion para el Estudio de los Antiguos Alfabetos Filipinos and in 1887, published his essay El Sanscrito en la lengua Tagalog which made use of a new writing system developed by him. Meanwhile, Jose Rizal, inspired by Pardo de Tavera's 1884 work, also began developing a new system of orthography (unaware at first of Pardo de Tavera's own orthography). A major noticeable change in these proposed orthographies was the use of the letter ⟨k⟩ rather than ⟨c⟩ and ⟨q⟩ to represent the phoneme . In 1889, the new bilingual Spanish-Tagalog La España Oriental newspaper, of which Isabelo de los Reyes was an editor, began publishing using the new orthography stating in a footnote that it would "use the orthography recently introduced by ... learned Orientalis".
