The spelling U:tl:proscribed spelling is discouraged by the Komisyon sa Wikang Filipino (KWF) under its new orthographical rules because it uses three or more consecutive consonants, which do not follow the native syllable structures of consonant-vowel or consonant-vowel-consonant. Words spelled with ng and a consonant, and vice versa counts as two consonants, and are exempted. Exceptions apply in loanwords where it is originally spelled with a triphthong but respelling them to follow Tagalog syllable structure is not applicable. See Appendix:Tagalog orthography for more details.
This template is used in the Usage notes section in Tagalog entries that use three or more consecutive consonants in spelling, which are proscribed by the Komisyon sa Wikang Filipino (KWF). This template is intended to be used with {{tl-superseded spelling of}}, though it can be used alone.
