Split an array into two array

I have an array or string, I am trying to split it into multiple arrays.

Input Array : {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"}

Output Array: { {"One","Two","Three","Four"},{"Five","Six","Seven","Eight"},{"Nine","Ten"} }

    a!localVariables(
      local!singleArray: {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"},
      local!lengthOfSingleArray: if(
        a!isNullOrEmpty(local!singleArray),
        0,
        length(local!singleArray)
      ),
      if(
        local!lengthOfSingleArray = 0,
        {},
        a!localVariables(
