"A horse and an elephant"
Translation:Koń i słoń
If you still can't type Ł, you can install a Polish keyboard layout on a PC or on a smartphone.
For Windows, open up the Windows menu from the taskbar and search "Region & language settings", go there and press "Add language".
For Android, go to "Settings" and scroll down to the bottom and press "Language and input", then "Samsung keyboard", then "Add input languages". I assume it's similar on an iPhone, either way it will be in some sort of settings.
