* **child** - This is a more general word than //son// or //daughter//, but it still denotes kinship with the father. Paul uses this as a metaphor for his love for Timothy. (See: [[en:ta:vol1:translate:figs_metaphor]])
* **engage in the good fight** - "participate in a struggle that is worth the effort" or "work hard to defeat enemies." This is a metaphor that means "work hard for the Lord" (UDB). (See: [[en:ta:vol1:translate:figs_metaphor]])
* **have been shipwrecked in respect to the faith** - Paul uses another metaphor to compare the condition of their faith to a ship that has been wrecked on the rocks. The metaphor means "what has happened to their faith is a disaster" (UDB). You should use this or a similar metaphor if it will be understood in your language.
* **they may be taught** - "that God may teach them"
