Tagalog grammar checked with the reason attached

Paste Tagalog and every issue is underlined where it happens, labelled spelling, grammar, punctuation or style, with the reason attached. Tagalog is written in the Latin alphabet, and ng and nang, verb focus and aspect, the linkers -ng and na are what a checker has to get right in it. This one shows the rule each time, not just the change, so you can accept the fix, ignore it, or learn from it.

How to check Tagalog grammar

Three steps. The third is the one most checkers leave out.

1

Paste or upload the Tagalog

Type, paste or drop in a document. Tagalog is already selected as the language on this page; the menu above the editor also offers the variants described below. If the text turns out to be something else, the detector says so and you can change it.

2

Read the flags

Every flag is underlined in the text and listed beside it. Spelling and grammar flags are errors; punctuation and style flags are judgements, and the label tells you which is which before you decide.

3

Accept, ignore or read why

Click a flag to see the fix and the rule behind it, then accept it or ignore it. Tagalog has rules that speech does not reveal, and the reason is there so the same error is not made twice.

What the checker looks at in Tagalog

The parts of Tagalog grammar and spelling where a checker has to know the language, not just the words.

  • AgreementTagalog has no gender, no case endings on nouns and no adjective agreement; instead the markers ang, ng, sa (and si, ni, kay for names) mark the role of each noun phrase, and the linker (na or -ng) joins a modifier to its noun (magandang bahay, bahay na maganda).
  • VerbsVerbs mark focus (actor, object, location, benefactive) and aspect (completed, incompleted, contemplated) with affixes and reduplication: kumain, kumakain, kakain; kainin, kinakain, kakainin. The focus decides which noun takes ang, and a mismatch between verb focus and marker is the central grammar error.
  • Spelling and diacriticsStandard Filipino is written without diacritics, although the stress and glottal marks (pagdiriwáng, batà) appear in dictionaries and careful text. The checker does not require them.
  • PunctuationStandard punctuation. The hyphen appears in reduplicated words (araw-araw), and between a prefix and a capitalised or loan root (mag-Facebook, mag-jogging), as the Komisyon sa Wikang Filipino specifies.
  • Capital lettersDays and months are capitalised (Lunes, Enero), as are languages and nationalities (Tagalog, Pilipino, Filipino). Titles with a name are capitalised (Ginoong Reyes).

Common mistakes in Tagalog writing

Five errors Tagalog readers notice at once, and what the checker does with each.

ng or nang

Ng marks possession or a non-focus object (bahay ng kaibigan, kumain ng mansanas); nang means when, so that, or marks an adverb (kumain nang mabilis). The most searched Filipino spelling question.

The linker

Magandang bahay, not maganda bahay; bahay na malaki, not bahay malaki. A modifier and its noun are joined by -ng after a vowel or n, and by na after other consonants.

Verb focus and the ang phrase

Kumain ang bata ng mansanas (actor focus) against Kinain ng bata ang mansanas (object focus). The affix and the marker must agree on which noun is in focus.

Missing hyphen before a loan root

Mag-jogging, nag-email, i-download: a Tagalog affix on a foreign or capitalised root takes a hyphen.

Missing po and mixed pronouns

A letter to a customer or an elder uses po and kayo or ninyo, consistently. Salamat without po in that context, or ka after kayo, is a register error.

Formal and informal Tagalog

Po and opo, the plural pronouns kayo and ninyo for one respected person, and the honorific verb forms mark respect; a formal letter without po, or a text that switches between ka and kayo for the same reader, reads as wrong.

The checker flags a mixed register as style rather than as an error, so the decision stays yours. If a whole text needs to move from one register to the other, the tone changer rewrites it in one pass.

Tagalog grammar checker FAQs

Is the Tagalog grammar checker free?

Yes. Check Tagalog without an account, within the per-check and daily word allowances shown beside the editor. Signing in raises them, and Pro removes the guest limits and the ads. The pricing page lists what each plan includes.

Which Tagalog does it check?

The checker accepts Tagalog and Filipino, the national standard built on it, including the wider Filipino alphabet with the letters c, f, j, ñ, q, v, x, z in loanwords. Tagalog is preselected on this page; change the language menu above the editor if the text is a different variant.

Does it correct Tagalog spelling as well as grammar?

Yes, and in Tagalog the two overlap. The Komisyon sa Wikang Filipino sets the standard. The errors met most are ng against nang, the linker dropped or doubled, the hyphen before a loan root, and the choice between native spelling and loan spelling for the same word (kompyuter against computer, both accepted in different contexts). Each of these is underlined where it happens, labelled spelling or grammar, with the standard form and the rule beside it.

Will it rewrite my Tagalog?

Not unless you ask it to. A check corrects what is wrong and leaves your sentences as you wrote them; every change is a separate flag you accept or ignore. The Improve and Rewrite passes, which do change wording, are separate buttons, and the paraphraser is a separate tool.

Can I check a whole Tagalog document?

Yes. Paste the text or drop in a .docx, .pdf or .txt file; the document is checked paragraph by paragraph and the corrected version can be copied or exported. Long documents are checked within the per-check allowance and continue as you scroll.

Is it useful if I am learning Tagalog?

That is where the reason attached to each flag earns its keep. Tagalog has no gender, no case endings on nouns and no adjective agreement; instead the markers ang, ng, sa (and si, ni, kay for names) mark the role of each noun phrase, and the linker (na or -ng) joins a modifier to its noun (magandang bahay, bahay na maganda). A learner sees which rule was broken, not just the corrected word, and can accept the fix or read why it was raised before deciding.

After the check

Translate the corrected Tagalog, change its tone, or shorten it. One plan covers every tool.
