Grammar Notes & Usage Tips
•Conjugation Basics**: As an i-adjective, 細い (ほそい) follows the standard i-adjective pattern. For past tense, change the い to かった, so "was thin" becomes 細かった (ほそかった).
•Negative Form**: To say "not thin," change 細い to its negative form by replacing い with くない, resulting in 細くない (ほそくない).
•Particle Pairing**: When describing something as thin, use the particle が or は. For example, 鉛筆が細い (えんぴつがほそい) means "The pencil is thin."
•Comparisons**: When comparing two objects, 細い can be used with より to say one is thinner than the other. For example, このペンの方があのペンより細い (このペンのほうがあのペンよりほそい) means "This pen is thinner than that pen."
•い-adjective: Conjugates by changing the い ending
