What is the 3 form of shine?

The three forms of shine refer to its conjugation as an English verb, and there are two acceptable patterns because shine has both regular and irregular uses depending on meaning. For the most common intransitive meaning, to emit light or to be bright, the three principal forms are shine in the base form and present tense, shone in the past tense, and shone in the past participle. For example, today it shines, yesterday it shone, it has shone all week. This is the form used for the sun shines, her eyes shone, his shoes shone. For the transitive meaning, to polish or to make something shiny by rubbing, such as to shine shoes, the three forms are typically shine, shined, shined. For example, I shine my shoes every morning, I shined my shoes yesterday, I have shined my shoes. Some style guides accept shone for both meanings, but American English often distinguishes shined for the polishing sense. So you need to choose based on context. If you mean to give off light, use shine, shone, shone. If you mean to polish, use shine, shined, shined. Both are correct, but shone is more common in British English overall.
