The word is made up of 'Rat' (advice) and 'Schlag' (strike, blow). The meaning is not literal, but rather an old expression for 'a kind of advice' or 'a suggestion'.
Sein Ratschlag war wie ein Weckruf für mich.
His advice was like a wake-up call for me.
'Ratschlag' (advice) is often combined with certain verbs. You can 'geben' (give) someone a piece of advice, 'bekommen' (get) advice from someone, or 'befolgen' (follow) a piece of advice.
Er hat mir den guten Ratschlag gegeben, mich mehr zu entspannen.
He gave me the good advice to relax more.
When you want to describe the content of the advice, you often use an infinitive construction with 'zu' (to) or a subordinate clause with 'dass' (that).
Ich gab ihr den Ratschlag, sich direkt bei der Firma zu bewerben.
I gave her the advice to apply directly to the company.
advice / council
'der Rat' and 'der Ratschlag' often mean almost the same thing: a recommendation meant to help someone with a problem or decision. Both words fit in many everyday situations. 'Rat' is a bit more general and also appears in fixed expressions, for example 'um Rat bitten' (to ask for advice). 'Ratschlag' sounds a bit more concrete: it is usually one specific tip or suggestion. In many sentences, however, you can use both words without much difference in meaning.
