If you’ve been minimally affiliated with any Judeo-Christian institution… ever, you’re familiar with the word אָמֵן (ah-MEN) – amen. The three-letter root of the word makes up the entire word. Its core meaning is trust.
Thus the word for reliable is אָמִין (ah-MEEN), or אָמִינָה (ah-mee-NAH), when speaking of a female or a feminine object.
For example, זֶה רֶכֶב אָמִין (zeh REH-khev ah-MEEN) – This is a reliable vehicle.
