When speaking to someone using a foreign language you may be able to cut a few corners and be forgiven for a couple of mistakes by setting the tone of the conversation.
Setting the tone means to lead the nature of the communication during the interaction. Going first and making your point clear tonally goes a long way in getting your message across, regardless of any language barriers.
A simple example of this could be when asking someone for directions. To set the tone of the interaction make it seem like you are asking for directions! It may seem confusing to comprehend, but making it obvious you are looking for something will send a message through your body language and the tone of the interaction.
Try not to be concerned with the fact you don’t quite speak their language. Worrying too much about that will simply send the tonal message that you don’t quite speak the language. As opposed to what you are aiming to communicate.
