What is an adverb in Tagalog?

In Tagalog, an adverb is called a pang-abay. It's a word that modifies a verb, an adjective, or another adverb, providing information about:

* Time: _kahapon_ (yesterday), _ngayon_ (today), _bukas_ (tomorrow)

* Place: _dito_ (here), _roon_ (there), _sa labas_ (outside)

* Manner: _mabilis_ (quickly), _dahan-dahan_ (slowly), _maingat_ (carefully)

* Degree: _sobra_ (very), _napakabuti_ (very good), _medyo_ (somewhat)

* Frequency: _lagi_ (always), _madalas_ (often), _minsan_ (sometimes)

Examples:

* _Mabilis na tumakbo ang aso._ (The dog ran quickly.)

* _Maganda ang bahay na ito._ (This house is beautiful.)

* _Sobrang masarap ang pagkain._ (The food is very delicious.)

Here are some other examples of pang-abay in Tagalog:

* pang-abay ng panahunan: (adverb of time) _kailanman_ (ever), _pagkatapos_ (afterwards), _kaagad_ (immediately)

* pang-abay ng lugar: (adverb of place) _saanman_ (anywhere), _malapit_ (nearby), _sa itaas_ (above)

* pang-abay ng paraan: (adverb of manner) _maayos_ (properly), _malakas_ (loudly), _walang kahirap-hirap_ (effortlessly)

* pang-abay ng tindi: (adverb of degree) _talaga_ (really), _lubos_ (completely), _napakasama_ (very bad)

* pang-abay ng dalas: (adverb of frequency) _bihira_ (rarely), _palagi_ (always), _madalang_ (infrequently)

It's important to note that the position of the pang-abay in a sentence can affect its meaning. In general, they usually precede the verb or adjective they modify.
