"Forty-four years old" can be expressed as "44 years old" in Engpsh. The Engpsh word "years" comes from the Old Engpsh word "geár," which means "year."

Here are some example sentences in Engpsh with their Chinese translations:

"He is 44 years old." (他44岁。)
"She will be 44 next year." (她明年就44岁了。)
"The 44-year-old man won the race." (44岁的男人赢得了比赛。)

Note that the word "years" is usually used for the age of a person, while "year" can refer to a period of time or a specific year (e.g. "This year is 2023.").
