When in Rome...try speaking Italian.
Those who speak English as their first language enjoy the distinct benefit of its function as a lingua franca across many communities and cultures, especially in tourism. It can, therefore, be tempting for travelers to forego learning any of the local languages, especially in countries where English is commonly understood.
These days, translation apps make it possible to hold more complex (albeit halted) conversations in other languages, regardless of comprehension. On top of that, speaking in an unfamiliar language can be intimidating, and many people are deterred by a fear of making mistakes or being misunderstood. But learning a few basic words can be an easy way to endear yourself to people and possibly yield some unexpected benefits.
Accuracy is often perceived as secondary to the effort, and attempts at speaking the local language can inspire the listener to be more helpful and engaged. A good strategy is to start with the more obvious and necessary words and, if there is any headspace leftover, expand into words or phrases that could make life easier or dazzle the native speakers.
