たものだ (ta mono da)
~たものだ — nostalgic “used to ~”
Pattern
-
動詞た形 + ものだta-form + ものだ (泳いだものだ, 話したものだ) -
動詞ていた + ものだte-ita form for a state that continued (広がっていたものだ)
Meaning and connection
The ta-form states the past event, and ものだ adds the speaker's feeling of looking back fondly. 子どもの頃、よく泳いだものだ means “I swam so often back then (and I miss it).” It attaches to the plain past form of a verb.
When to use it
Use it to tell memories of your childhood, school days or an old town. The habit has ended, so it is not used for the present or for a single event.
Difference from ~ていた
~ていた just describes a past habit or state. ~たものだ also expresses nostalgia. Adding よく, 昔 or 頃 makes the sentence sound natural.
Examples
-
子(こ)どもの頃(ころ)、よくこの川(かわ)で泳(およ)いだものだ。
Kodomo no koro, yoku kono kawa de oyoida mono da.
When I was a child, I used to swim in this river often.

学生(がくせい)の頃(ころ)は、友(とも)だちと朝(あさ)まで話(はな)したものだ。
Gakusei no koro wa, tomodachi to asa made hanashita mono da.
Back in my student days, I used to talk with friends until morning.
-
昔(むかし)は、この辺(あた)りにも広(ひろ)い畑(はたけ)が広(ひろ)がっていたものだ。
Mukashi wa, kono atari ni mo hiroi hatake ga hirogatte ita mono da.
Long ago, wide fields used to spread out around here too.
ていた + ものだ recalls a scene that is now gone.
Common mistakes
- It is only for past habits that have ended. Do not use it for a one-time event or something still happening.
- Do not confuse it with a general-truth ~ものだ (as in 子どもは遊ぶものだ). Here it follows the ta-form and is nostalgic.
